How does InkDrop work if I purchase twin packs?
With InkDrop, we send you the exact quantity and model number of what you have mailed back to us. If you send one empty cartridge, we will send you one replacement. If you send both empties from a twin pack, we will send you a replacement twin pack. It is recommended that you send both cartridges to get the added savings of a twin pack. If you plan to do this, it is a good idea to stock up on multiple twin packs. That way, when you send your empties, you won’t be without cartridges while you’re waiting for your replacement twin pack.
