I am a BIG fan of the Office Depot/Office Max Rewards program. You purchase items and then at the end of the quarter they load credit into your account. It’s basically like earning an Office Depot/Max gift card. I get all my ink and paper this way and you can use the rewards when you shop online.
Right now you can buy up to 10 Office Depot Brand Heavy Duty Binders and get 100% back in rewards. That’s like getting them FREE!
And if you don’t need them consider donating to hurricane relief!
