I found this really fun shopping app a few weeks ago. It's set up so well! All you need to do is list the item you want to sell at a price you'd be willing to give 20% off the top away. When someone buys it, you get emailed a free shipping label. (You can get free shipping packaging from usps.com.) There are no returns. It's the most hassle free shopping app I've ever seen. I'm loving it!
Join POSHMARK to buy and sell your fashions! I'm going to start listing a bunch of items. If anyone is interested let me know!
