http://www.imnotatwork.com/locations/52/New-York-City-NY offers a member card which gets you drink specials, many of which are 24/7, at bars around the city (examples: $2 off draft beers at Mercury Lounge, 10% off 3 bottles of wine at September Wines in LES, 64 oz pitchers of brandy infused sangria at Hop Devil Grill). Most of these bars aren't really places you'd want to hang in (Off the Wagon, anyone?) but cheap booze, is, well, cheap booze.
The membership currently costs $25 per year, and if you mention the coupon code "cheaptoboot" you get 20% off until the end of December. Take a look at their site to see if it's worth your while.
