For the longest time Staples had a deal with Hewlett-Packard and a few other companies that offered this: if you brought in an empty one of that brand ink or toner cartridge to Staples for recycling, Staples would give you a coupon for money off your next purchase of an ink or toner cartridge.
Now it seems that Staples is giving you $3 back on any brand cartridge you bring in for recycling. Of course the catch is that you have to be a Staples Rewards member to get this $3 “refund”, and that refund arrives in the form of a rewards check. And you’re limited to recycling 10 cartridges per month.
But signing up for Staples Rewards is free, so why not do it? And even if you did have 10 cartridges to recycle, that would be $30 back in your pocket (eventually) just for doing right by Mother Earth.
