We purchased diplomas from DiplomaPrinters.com, backed with proof of purchase, and then judged them on product quality (does it match real diploma?), service and value. Read our full review. Current customer feedback is at 98.9% positive as we speak.
One of the worst sites we have encountered in some time. We get a lot of people each month who wired money to the owner and nothing came. They then threaten customers if they refuse to report this. This is what I am hearing. Formal review to come.
