1.) Money Back Warranty – You should be able to get 100% of your money back if the aftermarket cartridge does not work properly. The longer the guarantee the better. 60 days is not enough so make sure you get at least one year from the purchase date.

2.) ISO-9001 Certification - A company that has been through the certification process makes sure the compatible and remanufactured cartridges offered work the same as original cartridges made by the printer manufacturer.

3.) Customer Reviews - Online printer ink retailers should show what customers say and also be rated by customers in sites such as Bizrate, pricegrabber, shopping.com to name a few.

4.) Buy from a store with Huge Inventory. Last week we shared the reasons why is important to check out what else is in stock. Check it out! Reasons to Buy Compatible HP C9730A Toner from a Store with a Huge Inventory

5.) Is the online a Social Store? The more the printer cartridge website allows users to connect or share product information on their favorite social sites the better. You know they are going to stay around and not run away with your hard earned cash.

6.) Live Customer Service Help. Fake places won’t have a live person ready to answer your questions. If you can call a toll free number then you know they want your business.

7.) Offer online purchase security. The site should have daily security test such as McAfee Security to ensure your credit information and personal data is secure.
