So this sounds like it could be either a really great idea or a really bad one, but its not too good to be true. You can ride the "all-you-can-drink" tequila train in Mexico.
According to Mental Floss the prices start at $111. Averaging a shot of tequila at around $10 to $12 a shot, that's a lot of shots to kill to break even. Would you go for it?
