to buy a movie you haven't seen yet
"Everyone's been telling me Gladiator is really good, so I decided to risk a Blind Buy."

Get the blind buy mug.
Selling something but not saying what it is and implying it might be worth the price. A way to sell something for more than it’s worth. A good of example would be doing a blind buy for a song that nobody really wants for $5k, when the most you would get for that song if it wasn't blind is $2k.

Why would people fall for this?
1. A drought of music and they'll settle for anything
2. Gambling "what if it's the song I want"
3. Retardation
"Oh boy I hope they're selling the song I want in this Blind Group Buy, I'll donate $100 and keep my fingers crossed."

Get the Blind Group Buy mug.
To impulsively purchase an item that you've yet to try/experience with the hopes that it turns out for the best. (Generally something that's received a bit of hype).
Sauvage Dior was a blind buy for me, but I ended up liking it.
