first post: Do you have a rental car? If so, go to Lee's Discount Liquor (20 locations) or Total Wine and Spirits (2-3 locations). You could also look at the Orleans, Gold Coast or Sam's Town for low cost liquor.

Here is another interesting post, with prices
HI,

From the looks of it, the prices are really fair.
If you click on the name of the store, it will give you the phone number, address, and map.

Thanks a ton Rueful Renard for the information and links, hopefully this should help getting the nippon beauties.

Vikas, you are most welcome!
