I went to buy an ink cartridge for my brand-name computer printer at a well-known discount store. The price for a single black cartridge? $49.88. I could have bought a printer - complete with ink cartridges - for $59! The ink cartridges are sold in plastic containers that can only be removed at the checkout. The operator told me that was because they were among the most-stolen items (along with razors, CDs and DVDs apparently). At those prices for some plastic, simple circuitry and ink, it's no wonder.
