Home Depot’s branded financing options can only be used to pay for purchases made at Home Depot. Unlike general-use credit cards, store-branded credit cards can typically only be used at the issuing retailer. So of course, you could not use a Home Depot credit card to make a purchase at Lowe’s. If you think you’ll need to finance purchases from other stores, it could be worth considering alternative financing options, such as a 0% interest credit card or a personal loan.
