Without any hesitation, I research all of the shops on eBay and find the best buy for my money. I never pay over $3.00 for my cartridges. However, my sister just bought an HP, bad choice, they require some of the highest priced cartridges. I have a wonderful Canon printer and never buy cartridges at a store. I might add that I have never once had problems with any of the eBay purchases in the last 6 years or so.
