Simple, Transparent Pricing

Yes! The Free tier is completely free. You can compare all portals, add 2 cards, and track up to 3 stores. Premium features have a 7-day free trial with no credit card required to start.

After your trial ends, you'll be downgraded to the Free tier unless you subscribe. You won't lose any data - premium features will just be locked until you upgrade.

Absolutely. No long-term contracts, no cancellation fees. Cancel anytime from your account settings and you'll keep access until the end of your billing period.

The answer depends on your spending and shopping habits. Premium users can earn $1000+ per year by catching AI-scored hot deals, syncing card-linked offers, and stacking portal cashback with credit card rewards. The $150/year plan pays for itself quickly.

We accept all major credit cards. Your payment info is securely stored and never touches our servers.

Never. We make money from subscriptions and affiliate commissions when you use portal links. We don't sell your data or show ads.

Cashback stacking means layering multiple savings on a single purchase — for example, shopping through a portal for cashback, paying with a rewards credit card, activating a card-linked offer, and buying a discounted gift card. CashBackStacks finds and combines all available layers automatically so you never leave money on the table.

The CashBackStacks extension is available for Google Chrome, Firefox, and all Chromium-based browsers.

No. The website works standalone — you can browse deals, compare rates, check offer history, and use the AI assistant without installing anything. The extension adds automatic store detection, popup stacking, search badges, and card-linked offer syncing while you shop.

Card-linked offers are merchant-specific credits attached to your credit or debit card by your bank (Amex, Chase, Citi, Capital One, etc.). When you activate an offer and make a qualifying purchase, the cashback or statement credit is applied automatically — no coupon codes or portal links needed. CashBackStacks syncs and displays these offers alongside portal rates so you can stack them.
