I have bought NUMEROUS times from them and love everything I get. There are some things I am not happy about and I will share them here. First, I believe there needs to be all sizes in kids. I like looking at items smaller than 12 months. I also wish they would try to sell items as a set and not so many individual things. Second, some things are not labeled correctly. Whether this be is labeled as a dress (when it is a top) or the wrong brand, they need to be careful when listing an item. Last, when you get "credit" for someone ordering something from your link you should be getting "Your credit is about to expire." No where did I read that any credit expires. I even won a $50 gift card and they kept sending my messages that it was about to expire.
I have never sold anything to them and never plan on doing so because I hear nothing but horror stories and see what the seller gets for the items (which is pennies on the dollar). I've only had one problem with a return but they paid for the return (it was listed as Gymboree and it wasn't) and that went smoothly.
