Not a clothing sale...but may be of use to people. If you have a Discover IT card, you can call them today to ask for the double cashback promotion. At least 2 months of double cashback, many people are reporting a full year of double cashback.
*edit* Just did it myself. Got a full year's worth. You won't get the double cashback until after 12 billing cycles, must still be a cardmember. Double cashback won't apply until your next cycle. The US based rep just had to double check my account was eligible for it, told her I just read about it online - no personal invitation needed.
