Gap has some decent stuff in the sale section, 50% off plus free shipping. 40% off is pretty normal, so this isn't incredible but there's a few gems in there (I hope).

Notably, Button down collar polos for $6 in black or grey with good size availability. No experience with these in particular, but for $6 hard to go wrong. Some decent cardigans in there too.

Codes needed - EXTRA for 50% off sale, and SHIP for free shipping.

8% cashback with e-bates too, or if you've picked up the gap options gift cards that go on sale for 20% off pretty often, you can get stuff for almost nothing.

Watch for final sale items.

EDIT: Fixed the code!
