like plato's closet, i've only sold here so my review is on the selling experience alone. basically you bring your clothes in, and they sort through them deciding which ones they will sell for you. every time i've gone to this location, they've quoted a 5 to 10 minute wait and finished within the quoted range.
i like that they are quick. i like that they usually take most of my stuff. i like that they will donate the rejects for me.
what i don't like is that they are not very friendly or welcoming or appreciative of me bringing in my clothes for them to make money off of. i also don't like the whole idea of consignment because i never really know what sold and what they got for it and what they gave me.
you just go back a few weeks later and check your account to see if you've earned any money. there's a lot of trust involved. ebay is definitely the way to go if you really want to get the most for your clothes, but if you don't have time this is an ok alternative.
