Gap slashes 25% off sitewide via coupon code "GAPFALL25." That's tied with last month's discount and is one of the better deals we've seen from Gap in recent months. Shipping adds $7, or get free shipping on orders over $50. Sales tax is added where applicable and some exclusions apply. Deal ends September 9.
A best bet is the Gap Stretch Poplin Shirt in Midnight Purple for $29.99 before the above coupon, $22.49 after. With $7 shipping, that's $22 off list and the lowest total price we could find. It's available in S to 3XL.
