They sent me a cartridge that didn't work in my printer - this after I called to make sure I was ordering the correct one. Their site says they guarantee 100% satisfaction, but although they refunded me for the faulty cartridge, they would not refund the $5.35 I paid in shipping. They said the shipping service had been performed so there was no refund. Every other company that has ever sent me a faulty product has refunded the shipping costs. The fault was theirs, but I have to swallow the shipping cost. I ordered a cartridge for less than half the price from Greencycle, with no shipping charge, and it works perfectly. I will not be buying from 123Inkjets again!
