Tip 1) – Demand ISO-9001 Certification. By checking if the cartridges have been made by ISO 9001 certified companies you rest assure they follow strict guidelines and that the cartridges are of good quality. Be sure that places that have this certification will sell you decent products.

Tip 2) – 100% Money Back Guarantee. Serious online ink vendors know that stand by their products will offer you a full money back guarantee at all times. So look for such guarantee to be displayed in their landing page and not hidden elsewhere.

Tip 3) – Live Customer Service Help. Just because they have discount prices doesn’t mean they have to be cheap about their services. You need to know they’ll stand by you and you can contact them more ways than one. So look for a Toll Free number (why should you have to pay for the call) a live chat option and obviously an email to ask for help is important. Now with all the Social media advantages you should seek for the companies Twitter and Facebook accounts.

Tip 4) No less than 1 year warranty. You want to have a long standing warranty in case something happens to cartridges. Also a year warranty allows you to buy more than one cartridge at once and save on shipping charges. If you know how much a cartridge last you can purchase replacement cartridges at the same time and not worry about issues for an entire year.

Tip 5) – Make sure they have a large inventory. We talked about this on a previous post called: Reasons to Buy Compatible HP C9730A Toner from a Store with a Huge Inventory. “So what you need to look for when purchasing from such places is verify if they cater the demand of the huge printer user market. That means that the more brands and types of cartridges they have the better because a company that has such a large inventory will do it’s best to provide top quality service and products to its customers.”
