If you're not already shopping for clothes on Amazon, you might want to give it a try! The company is rolling out a pilot test of something called Prime Wardrobe, which will make Amazon Prime even more tempting. According to the company, it will let you try before you buy clothes. Simply pick 3 or more items from Amazon Fashion—clothing, shoes, and accessories—to fill your box. Try the stuff on and return for free the items you don't want. The more you keep the more you save.
