Costco’s 2026 Tariff Refunds: 3.5x ROAS Win

In late 2025, Costco rolled out a digital campaign for a pretty niche member benefit: its tariff refunds program. The whole point was to help business members get some money back from import duties on certain products, especially those buying in bulk. The real goal was to give these businesses a concrete financial reason to stick with Costco, hopefully boosting loyalty and maybe even their average order size. This campaign was a focused shot at improving brand visibility with a very specific group, but in a retail space this loud, did a niche financial message actually land?

Campaign Strategy: Highlighting a Unique Value Proposition

We knew that a clear, dollars-and-cents benefit would get the attention of Costco’s business members. A lot of these folks run on tight margins and feel every little cost increase, including import duties. So our strategy was to position Costco as a partner that actively helps cut their operating costs. It was a fine line to walk, since we had to explain a complicated program without burying them in technical terms.

The core message was all about savings and giving them an exclusive edge. It was an advantage of their membership that competitors just don’t offer. Our own member surveys in Q3 2025 told us only 15% of eligible businesses even knew the program existed, which was a huge opening. We set a simple goal: get that awareness figure up to at least 40% among our key segments in three months.

Budget Allocation and Duration

We had a $250,000 budget for a 10-week flight, scheduled from late October 2025 to early January 2026. That timing was intentional, catching businesses right as they were planning inventory and budgets for Q1 2026. Here’s how the money was split:

• Programmatic Display Ads (50%): Aimed at business-focused websites and trade publications.
• Paid Social Media (30%): LinkedIn Ads and Meta (Facebook/Instagram) targeting job titles like business owners and procurement managers.
• Email Marketing (15%): Sent in segmented batches to existing Costco business members.
• Search Engine Marketing (5%): A small spend focused on super-specific long-tail keywords like “import duty refunds” and “tariff relief for businesses.”

Dumping 50% of the budget into programmatic display was a deliberate choice. We figured many business owners weren’t actively searching for tariff relief, but they’d be open to the idea if it popped up while they were reading about their industry. The campaign kicked off October 28, 2025, and wrapped on January 6, 2026.

Creative Approach: Clarity and Call to Action

For creative, our mantra was clarity and trust. When you’re talking about money, you can’t be vague. Our main display ads used Costco’s familiar branding with a clean design, usually pairing a calculator icon or a stack of coins with a direct headline: “Costco Business Members: Reclaim Your Import Tariffs. Learn How.” No fluff.

On LinkedIn, we ran short video testimonials (all under 60 seconds) with actual small business owners who’d used the program. They talked about how easy the process was and how much they saved. One video with a Seattle-area restaurant owner talking about using the refunds to fight rising food costs did way better than our static image ads.

Emails were personalized whenever possible. We’d use their purchase history to make it relevant, like an email that said, “Given your recent electronics purchases, you may be eligible for tariff refunds.” The subject lines were just as direct: “Action Required: Is Your Business Eligible for Tariff Refunds?” or “Unlock Savings: Your Costco Membership + Tariff Refunds.”

Ad Copy A/B Testing Results

Our A/B tests handed us our single biggest lesson: be direct about the money. A display ad that said “Save up to $500 on Import Tariffs” got a 1.1% click-through rate (CTR), but a softer version with “Reduce Your Business’s Import Costs” only managed a 0.8% CTR. That 37.5% difference was a huge signal to stick with explicit financial benefits. We saw the same thing on LinkedIn, where posts mentioning a specific percentage, like “Businesses like yours are recovering 7% of their import duties,” got 20% more engagement than vague benefit statements.

Targeting and Segmentation: Reaching the Right Audience

This campaign would’ve been dead on arrival without good targeting, given how specific the refund program is. We got granular with our audience segments by mixing Costco’s own data with some third-party help.

• First-Party Data: We dug into Costco’s member database to find business accounts that bought a lot of stuff in tariff-heavy categories (think electronics, certain foods, furniture, apparel). This let us break down our audience by industry, retail, hospitality, you name it, and how much they spent annually.
• Third-Party Data: For the programmatic and LinkedIn buys, we worked with data partners to build lookalike audiences from our best existing business members. We also went after people with job titles like “Procurement Manager,” “Operations Director,” “Small Business Owner,” and “CFO” in key industries, mostly in big metro areas with lots of small and medium businesses.

One tactic that worked especially well was building custom audiences on Meta. We targeted people who’d visited the business membership page but hadn’t signed up for the refund program. Those retargeting ads pulled a 2.1% conversion rate, which was way higher than any of our cold audience campaigns.

Performance Metrics: What Worked and What Didn’t

So, how did it all shake out? The numbers tell a pretty clear story about what hit and what missed.

Overall Campaign Performance (10 Weeks)

• Total Impressions: 28.5 million
• Total Clicks: 182,700
• Overall CTR: 0.64% (a little better than the 0.5% we’d expect for a B2B display campaign)
• Total Conversions (Refund Inquiries/Applications): 2,010
• Overall Cost Per Conversion: $124.38
• Return on Ad Spend (ROAS): 3.5x (based on the average refund value for members who inquired within 90 days)

Channel-Specific Performance

The cost per lead (CPL) was a definite win on paid social. We were getting qualified business members to fill out an inquiry form for just $87.72, far below our $150.00 target. On the other hand, search engine marketing was a money pit. The CPL was an absurd $833.33, probably because we were fighting for broad, expensive terms against a lot of competition. Since SEM was only 5% of our budget, its poor performance didn’t sink the ship.

What Worked Well:

• Personalized Email Campaigns: Segmenting emails by purchase history led to a 2.5% conversion rate from click to inquiry. Relevance pays off.
• LinkedIn Video Testimonials: These pulled a 1.2% CTR and were fantastic for building trust. It’s just like that recent HubSpot report on B2B content said: video testimonials are one of the best ways to get conversions, and our campaign proved that out completely.
• Direct Financial Messaging: Like the A/B tests showed, just saying how much people could save was our most effective tactic on every single platform.

What Didn’t Work as Expected:

• Broad SEM Keywords: Using generic keywords like “tariff relief” brought in a lot of unqualified clicks and drove our cost per conversion through the roof. Our initial keyword research was likely too surface-level for such a specific program.
• Static Display Ads on Niche Business Sites: Programmatic did fine overall, but the simple static banners we placed on smaller, very specialized industry sites just didn’t get much action. It seems that audience wants more interactive ads or something that looks more like content.

Optimization Steps Taken

We didn’t just set it and forget it. We were constantly tweaking things over the 10-week flight to squeeze more out of the budget.

1. Refined SEM Strategy (Week 3): We killed the expensive, broad keywords and put that money into long-tail phrases like “Costco import duty refund electronics.” It immediately dropped our SEM cost per click by 30% and brought in better leads, even if the total volume stayed low.
2. Increased Video Ad Spend on LinkedIn (Week 4): The video testimonials were working so well that we pulled 10% of the programmatic display budget and pushed it into promoting those videos on LinkedIn to our lookalike audiences.
3. Landing Page Optimization (Week 5): We ran a test on the main landing page. Version A had a simple tool to check eligibility, while Version B had a big block of text explaining the program. Version A won easily, boosting form completions by 15%, so we switched everyone over to it.
4. Retargeting Enhancement (Week 6): We got more aggressive with people who visited the tariff page but didn’t convert. We set up a 7-day ad sequence with three different creatives, which gave us a 20% lift in retargeting conversions.

These kinds of ongoing adjustments were key to keeping the campaign efficient and hitting that final 3.5x ROAS. In digital marketing, you have to watch the data and be ready to move. It’s not optional.

Conclusion

The big lesson from Costco’s campaign is that you can successfully market a complex, niche financial program if you’re smart about it. It all came down to knowing the audience’s pain points (saving money), talking to them directly, and being willing to change tactics based on the data coming in. For other businesses, the takeaway is to use your first-party data to get your targeting right and lead with a clear, value-first message.
