I am trying to find ways to save money and my dad suggested to BYO alcohol and just pay the $15/per bottle corkage fee the venue provides. I'm not planning an open bar just Beer, Wine, 3 signature drinks. Do you think that buying the liquor from a place like Costco and then paying the corkage is worth it? I don't even know how much liquor I should buy for around 80 people. Do you only have to pay for the open bottles or just factor that you will use all of the bottles? Has anyone done this? What are your suggestions...im so confused.
