Revolveclothing - coupon matching, free shipping and free returns. You can buy a whole bunch of stuff, try it on, and return it. Plus their customer service is excellent. Credit card refunds have a quick 1 week turnaround time. I've shopped with them for the past year and a half with no problems, only good comments.
Love'em!
Shopbop.com has the best photographs but their customer service and shipping times leave little to be desired.
Regarding shopintuition - I have also heard similar comments, and I've never ordered from them. I would also avoid goclothing.com - their shipping is shoddy, slow, and sometimes the clothes arrive damaged (got a pair of Seven jeans with a permanent yellow stain).
