I'm very frustrated with my experience with Swap. I worked really hard and sent several boxes and they basically have told me that nothing I've given them is sellable.
It's super annoying to think you're sending off tons of boxes, and then GET THEM ALL BACK. On the site they specifically asked for women and children's items. I provided tons of books, clothes, and toys... and got them all back. I now am waiting for the last of the inventory I'm sure to be returned to me. It's no one's fault, it's just a big disappointment. Such wasted time.
