My Habit is a NEW members only designer store run through Amazon. They are definitely high priced clothing, but through 9/1/11 you can use code INTLSHIP to get $25 off any order. They also ALWAYS have FREE shipping and you can use Amazon gift cards since the site is run through Amazon.
New sales start everyday at noon EST, so HURRY and be ready. Anything $25 and under sells out immediately, BUT you have all month to try.
