couponpercentage

Couponpercentage refers to the percentage value used to determine the discount granted by a coupon in commerce. It is typically expressed as a percentage and applied to eligible merchandise at checkout.

In calculation terms, the discount amount equals the original price multiplied by the coupon percentage divided by 100. For example, a 20% coupon on a $100 item yields a $20 discount, reducing the subtotal to $80 before taxes and shipping.

Coupons may be subject to restrictions such as minimum purchase amounts, item exclusions, category limitations, or one-time-use rules. Many programs also limit coupon applicability to specific brands, products, or geographic regions. Some coupons can be stacked with other promotions depending on retailer policy; others block stacking.

The order of application varies by jurisdiction and retailer policy. In most cases, the discount is applied to the subtotal before tax, with tax calculated on the discounted amount. Shipping costs may be unaffected or reduced by the coupon, depending on policy.

Retailers often enforce expiration dates, usage limits, and maximum discount caps. Some customers encounter issues such as regional restrictions, insufficient balance, or invalid codes, which require customer support.
