Bulk alcohol

Costco and Sam's Club have the best deals, but will be less willing to negotiate with you. I'd start with their prices and then see if a smaller place can give you a discount for buying in bulk.

What about a keg from Total Wine? They have 1/4 kegs and other sizes. That might be a cheap option.

Where are these 5 cent wine sales and how do I find them? That sounds amazing! I would get a keg for beer and some cases of wine instead of individual bottles, or do some boxed wines in decanters

Find a BevMo near you. They have buy one, get one for 5 cents. I don't want to do a keg. It's not that casual of a party. I bought a big metal tub for ice and beer bottles.

I like the 5cent sale from Bevmo but I find that overall total wine has better prices for the nicer wines and spirits

Bevmo had Fidencio Mezcal for about $43... totally wine about $35

Also total wine give you a discount on wine if you buy 6 or more (on most)

I do like the service better at Bevmo but I'll take less than stellar service if I'm saving over $100 overall especially if you know what you're buying (brands and such)

By my house Bevmo is more helpful in that way but if I know what I'm going to buy ... total wine has better prices
