For every used ink cartridge you turn in using your Staples Rewards Card, you will get a $2 credit for use in-store or online! Last month I turned in 6 cartridges, and today I got an email with my $12 credit to use! Happy day!
Plus you’ll get 5% back in rewards on everything in store and online, and free shipping from Staples.com. If you’re not a member, I highly suggest signing up!
