Frequently Asked Questions
How does the discount stacking calculator work?
Enter the original retail price, then add each discount tier: store sale percentage, coupon value, cashback portal rate, and credit card reward rate. The calculator compounds these sequentially to show your true effective cost — not just checkout price. This gives you the exact buy cost to plug into profit calculators for accurate retail arbitrage margin analysis.
What is the difference between stacking discounts and a simple discount calculation?
Simple discounts apply one percentage to the retail price. Stacked discounts compound: a 30% sale, then a $5 coupon, then 10% cashback, and 2% credit card rewards reduce a $100 item to roughly $55.80 — not the $47 you get by naively adding percentages. This calculator handles the sequential math so you see the real effective cost for accurate sourcing decisions.
Which stores allow the most aggressive discount stacking for retail arbitrage?
CVS and Walgreens historically allow the deepest stacking — weekly sales, manufacturer coupons, store coupons, ExtraBucks, and cashback portals all compound. Target's RedCard plus clearance plus Rakuten typically produces 40-55% effective discounts. Grocery chains with loyalty cards, manufacturer coupons, and cashback apps like Ibotta can produce similar results on household goods.
Does cashback portal income affect my IRS reporting for retail arbitrage?
Cashback rewards from portals like Rakuten or credit card points are generally not reportable income — the IRS treats them as purchase price reductions. For Schedule C purposes, use your out-of-pocket cost (after cash discounts and coupons) as COGS. Cashback received post-purchase reduces your cost basis, which effectively lowers your deductible cost of goods.
What compound discount is realistically achievable in 2026?
Realistically 35-55% compound discounts are achievable at major drug and grocery chains by combining a weekly sale (20-30%), digital coupon (10-20%), and cashback portal (5-10%). At Target, RedCard plus clearance plus elevated Rakuten rates regularly hits 40-60% effective discounts. Credit card rewards (1.5-5%) layer on top whenever a portal runs a bonus window.
