We found a box of toner in our company supply closet that did not fit any printer we still own! It was still brand new, in a box, fully sealed. One staff member half-jokingly said 'you should sell it!' So I googled 'selling unused toner cartrideges.' Toner Connect popped up on the screen and it couldn't have been an easier process. I sent a photo of the unopened box and the model of toner and they sent a proposal (that we accepted) right away! Next came the shipping label. Within 2 days of shipment, I received word that they had the cartridge and our payment was being issued. More space in our supply closet and money in our pocket too! Win-Win!
