Frequently asked questions
What's a "stacked" discount?
Multiple discounts applied in sequence. 20% then 10% off is NOT 30% off — it's 28% off (because the 10% applies to the already-discounted price).
BOGO half off — how much off?
Buy one, get one 50% off = 25% off the total when buying two. Buy one, get one free = 50% off when buying two.
What's the catch with "up to X% off"?
Marketing language. Means SOME items have that discount, not all. Most items will be discounted less. Check actual prices.
Coupons and stacking?
Most retailers limit one coupon per purchase. Some allow stacking (manufacturer + store). Read terms; rules vary.
