Gap takes 20% off sitewide via coupon code "GOBIG". Plus, take another 30% off sale items via coupon code "EVENBETTER". (Both codes stack.) Even better, bag $20 in GapCash with every $50 order. (A $120 maximum applies; it can be redeemed between April 7 and April 15.) Shipping adds $7, but orders of $50 or more (before coupon) receive free shipping. Some exclusions may apply.
