Stuff purchased from the e-commerce branch of many popular stores are usually returnable at brick-and-mortar locations. While this is definitely less convenient than mailing it back, it sometimes results in finding something in the shop that you like better, and sometimes even a deal. Since most e-commerce and retail locations have different sale prices and stock, you might come up on an item you didn't know existed, or a really good sale price in the store, since items are more likely to be priced to move in a brick-and-mortar shop than online.
