Query: Need clearer product description

Admittedly, I haven't ordered it yet, but the title clearly says Scotch Photo Document Mailer 12/pkg - white which should mean you get 12 per purchase. Sounds good right? But if you read the fine print it says this package contains 1 envelope. So which is it? Am I getting ripped off at $5 per envelope or getting a great deal at 12 for $5?
