I've ordered from this site dozens of times. The only reason I didn't give a five star review is that the shipping is slow. But given I know that I just order stuff in advance (I am normally ordering a future size anyhoo). I haven't had one bad item (quality) at all in children's clothing and the one women's item I received that was really oddly sized they did accept back with a full refund despite their policy. (I sent them a picture showing that the arms were literally a foot too long).
For shoes and children's clothing I use this site almost exclusively. Occasionally I order housewares or women's items. I'd say that 99% of the time I'm thrilled with the items I receive, but then again I look at brand names carefully so I don't get an off item.
