Old Navy: President's Day Sale

It's the President's Day Sale at Old Navy! Starting today, get 15% off when you spend $50 or 20% off when you spend $75 when you use coupon code ONPDAY at checkout. Sale runs through 2/21 and is valid both online and in-store. The only exclusion that I see is that it cannot be used on jeans. Shipping is free when you spend $50.
