About Perk Cashback
Connect your card-linked offer sources (Amex Offers, Chase Offers, Capital One, Citi, PayPal) in CashBackStacks. It automatically checks for Perk offers and includes them in your total savings calculation.
It depends on timing — portal rates for Perk change frequently. CashBackStacks compares rates across 50+ portals including Rakuten, TopCashback, BeFrugal, and others in real time. Check this page for the current best rate.
The CashBackStacks stacking calculator lets you enter your Perk purchase amount and see savings from each layer — portal cashback, credit card rewards, card-linked offers, and discounted gift cards. It compares gift card rates across providers so you find the best deal.
CashBackStacks compares current rates against historical averages and flags deals with a fire rating (1-3 flames). If Perk's rate is above its baseline, you'll see it on the Hot Deals page. Money-maker deals (>100% back) are highlighted with a diamond icon.
Install the CashBackStacks extension and cashback badges appear automatically in your search results. When you search for Perk or related products, you'll see available cashback rates inline — no extra steps needed.
The Priceline Rewards from Barclays Bank earns 2% back on Perk purchases in the All Other category. You can stack this with portal cashback for combined savings.
