Amazon Local offers a coupon for $10 off orders of $25 or more at Woot for free. (Note that a credit card is required to complete the transaction, but you won't be charged. The coupon will be added to the "My Vouchers" page of your Amazon Local account.) That's tied with our March mention as the best dollar-off coupon we've seen for Woot. Limit one per customer. Deal ends August 21 at 3 am ET, and coupon expires September 20.
