Problem here is I have to go to the site every time I want to check for drink specials.

Why not some sort of push interface?

I've had this idea in the past, where people sign up to your SMS "newsletter" that lets them know about the best drink specials that night. Sort of a text-based Groupon for fratboys.

Bars and promoters could then pay you for access to your list, provided they had a good deal at the time.

I'm sure SendHub would love to help... in fact, I think I've told Ash about this idea a few years back :)
