Gap, Banana Republic, Old Navy, Piperlime, and Athleta are all having a 20% off Cyber Monday sale. Use promo code: MONDAY for 20% off your entire purchase and free shipping Monday, November 30, 2009.

I’d say this sale is slightly disappointing, as there have been some better coupon codes from the Gap family lately, but alas, it’s the holiday season now… so you’re out shopping anyway!
