Always keep your receipt and things will run a lot more smoothly. With a receipt, you are usually entitled to return clothes for up to 30 days from the time of purchase for a full refund, store credit, or exchange. This includes sale clothing. If, for some reason, you don´t have a receipt, you might be able to exchange the item for a different size, color, or equally priced garment but return policies will vary from store to store. Often the exchange must equal the original purchase amount exactly. And since you won´t get cash back without a receipt, even for a paltry sum, you´ll be expected to purchase more to “even” things out.
