Have you ever used ThreadFlip? (plus: blatant self promotion)

Tulle brand jacket I am selling on ThreadFlip.

I've already explained that I'm trying to sell off some of my belongings before I move and why. I'm also donating a shitload of things, but it's those items that I really like, but rarely use/wear, and am ambivalent about that I'm trying to sell. Do you know what I mean? I like them too much to give them away, but if I can get a little cash for them, I'll be content to let them go.

In addition to the blog sale, I put some of my clothing up for sale on ThreadFlip, a clothing and accessories reselling site. This is my first time selling clothes. I know that Ebay would be another option, but for some reason I've always found it intimidating to buy or sell clothes, in particular there. ThreadFlip is pretty easy to use. You upload a couple of photos, fill out a form to create a detailed description of your item, and choose a price range. ThreadFlip takes a 20% commission from every sale, and the minimum price you can charge for an item is $10.

I'm genuinely curious to hear about others' experiences selling used clothing. Have you taken it to a consignment shop? Sold it on Ebay or somewhere else online? What do you think is best?
