Capital One Shopping (formerly Wikibuy) offers solid coupon finding — but locks its best features behind a Capital One card. Here's how PromoIQ compares when you just want to save money, no bank required.
| Feature | PromoIQ | Capital One Shopping |
|---|---|---|
| Credit Card Required | ✓ No — works for everyone | △ Free to use, but best rewards need Capital One card |
| Checkout candidate testing | ✓ Source-grounded candidates only; checkout result decides | ✓ Solid auto-apply with decent coverage |
| Price Comparison | ✓ Available when a current source-backed offer can be verified | ✓ Good price comparison with seller ratings |
| Rewards Program | ✓ Savings tracked, referral rewards, premium perks | △ Shopping Credits — but best rates locked to Capital One cardholders |
| Privacy | ✓ No background tracking. Runs only when you click. | ✗ Collects browsing + purchase data for Capital One |
| Code confidence | ✓ Unverified until checkout proves a result | △ Decent but no user validation system |
| Data Collection | ✓ Zero — no purchase history stored | ✗ Feeds data to Capital One's financial profiling |
| Bank Affiliation | ✓ Independent — no corporate agenda | ✗ Owned by Capital One Financial Corp. |
| Watchlist/Alerts | ✓ Price alerts (premium feature) | ✓ Watchlist with price drop notifications |
| Unavailable outcomes | ✓ Says when no safe candidate or price match is available | △ Moderate — similar to Honey's approach |
Capital One Shopping is technically free for anyone. But here's the catch: the best rewards rates, Shopping Credits bonuses, and exclusive offers are reserved for Capital One cardholders. If you don't bank with Capital One, you're getting a second-class experience.
PromoIQ doesn't care who your bank is. Every feature works the same for every user. No tiered loyalty programs designed to funnel you into a credit card application.
Capital One Shopping is owned by Capital One Financial Corporation — a bank. When you use their extension, your browsing habits and purchase data flow into Capital One's ecosystem. They can use this data for credit decisions, targeted financial product marketing, and internal analytics.
PromoIQ is an independent company. We have no banking parent. No financial products to cross-sell. Your shopping data stays yours — we literally don't collect it.
A code-looking string is not a discount until the retailer's checkout total changes. Codes can be expired, targeted, or unavailable for a cart.
PromoIQ shows only syntactically credible, source-grounded candidates for the current retailer. They stay unverified until checkout proves a result; when no candidate is safe to show, PromoIQ reports that instead of inventing a code or apply action.
Both extensions offer price comparison, and Capital One Shopping does it reasonably well. PromoIQ can provide a direct product link when it has a current, source-backed match. When a destination price cannot be verified at click time, PromoIQ marks the offer unavailable and does not show savings math.
Choose Capital One Shopping if you already have a Capital One card and want to maximize their rewards ecosystem.
Choose PromoIQ if you want the best coupon extension regardless of your bank. No card requirements, no financial data harvesting, just smarter savings for everyone. We believe great deals shouldn't require a credit application.
No credit card required. No sign-up. No personal data, no browsing-history sale, only the current product page, only when you click.
