I have sold to Thredup for a few years and made over 1,000. I tried swap because they take more items. I sent a full box of quality items (I am not new to the process so I didn't send poor quality) and I received negative 21.90! I owe them money. IF all of my items sell I will make a whole 10 cents. I am not using this site again. Buying might be fine but please consider other options for selling!
