Your Cashback Keeps Earning

Unlike regular cashback that disappears into your bank account, Preffin cashback becomes local spending power. Use it at any participating business—and earn cashback on that too.

It's a loop that keeps giving back to you and your community.

Example

You've got $147.23 in local spending power. That's 29 coffees at Kaldis, or a nice haul at Left Bank Books. When you spend it, you'll earn ~$3.68 more in cashback.

Questions? We've Got Answers

Is Preffin really free?

Yes! Preffin is 100% free for you. No fees, no subscriptions, no catch. Local businesses and community organizations fund the cashback as an investment in the local economy.

How do I earn cashback?

Link your card once, then shop at participating local businesses like you normally would. Cashback is automatically credited to your account—no scanning receipts, no codes, no check-ins.

Where can I spend my cashback?

Your cashback becomes local spending credit you can use at any participating Preffin business in Saint Louis. This keeps money circulating in our community—and you earn cashback when you spend it too!

Is my card information secure?

Absolutely. We use bank-level encryption and never store your full card details. Your financial information is protected by the same security standards used by major financial institutions.

How much can I actually earn?

Most users earn $30-50/month just shopping where they already do. Power users who actively support local can earn $100+ monthly. Rates range from 1-2.5% depending on the merchant and any district bonuses.
