Start with the total, not the headline
A percentage discount can look more generous than it is. Add the items you actually want to a basket and check whether the promotion applies to all of them. A coupon limited to full-price products may leave sale items unchanged, and a minimum spend may exclude delivery charges.
Compare the final total, including shipping and any charges shown at checkout. Buying extra items solely to reach a coupon threshold can cost more than placing the smaller order without a discount.
Check what the code covers
Read the offer’s restrictions before copying the code. Common conditions include new-customer eligibility, selected collections, one use per customer, and exclusions for gift cards. Treat an unknown expiry as unknown, not as a promise that the offer will remain available.
Enter the code before paying and confirm that the order summary changes. If it does not, check spelling, basket eligibility, and the merchant’s current terms. A code listed on a coupon site is not a guarantee that it will work for every customer.
Choose the purchase before the promotion
Check the product’s specifications, sizing, care instructions, and return conditions first. A promotion is most useful when it reduces the cost of something you already intended to buy.
When comparing bundles, list the included items and consider whether you would use each one. An appealing bundle price is less useful when most of the contents would sit unused.
