I know there are tons of questions before on beer and wine in bulk and Sams Club and Costco are always suggested. I'm wondering mainly if anyone has used Sams Club before for wedding alcohol and if they have a wide variety of options? We have a Sams Club close to us, so FH really wants to get a membership to buy everything. But I've seen a lot more people suggest Costco on the forums, so I was wondering if anyone knew how much they differ in their brand options, if at all?
Also, do they both take unopened returns?
