Home Depot retail stores cut $5 offpurchases of $50 or more via a printable coupon when you sign up to receive emails. (Scroll down and click on the "orange insider" icon to sign up.) That's among the better dollar-off coupons we've seen from Home Depot recently, although we saw $5 off $25 or $10 off $50 via PayPal in December (since expired). Sales tax is added where applicable. Coupon expires February 17.
