OfferKnot: Deal Stacker

OfferKnot helps you compare checkout offers without confusing a lower payment today with real savings. Enter confirmed basket prices and reusable rules for percentage discounts, fixed discounts, cashback, gift cards, and free shipping. OfferKnot checks valid combinations and orderings locally, including thresholds, caps, expiration, exclusivity, and stacking rules. The result separates pay now, cashback later, true savings, gift-card funding, threshold gaps, and unused offers. Save the plan and export a PDF playbook, CSV calculation, or portable JSON backup. No account, cloud sync, live coupon feed, merchant login, bank connection, analytics, ads, tracking, or remote AI. Verify the result against the merchant's current terms before paying.
