"You then send a request to swap for the items of your choosing, the owner responds by choosing items of equal value from your own listings, and then you mail each other the packages.
Any time I need new makeup, instead of buying it, I can just browse the Swap Site for whatever I need and trade for just the cost of postage. The great thing is that most people swap based on the retail value of the makeup. So if you paid $21 for a box worth $100, you can turn it around and pick out $100 worth of stuff.
And there is so much more than makeup! Candles, jewelry, home decor, accessories, etc…you name it, it’s probably up for swaps." —dividedbyzero
