Ending today, PayPal cuts $5 offHome Depot in-store purchases of $25 or more or $10 off purchases of $50 or more when you pay in-store via PayPal. (You must add the desired coupon to your PayPal account via the above links.) That ties our mention from two weeks ago as the best such offer we've seen from PayPal for Home Depot purchases since early October, when we saw a $5 off $5 coupon. You can pay via PayPal in retail stores using either a cell phone number and PIN that you set up after adding the coupon to your account at the link above or a PayPal payment card that can be mailed to you at your address. Note that this credit cannot be applied to business accounts.
