Yes they still sell buckets, but the price has gone up since most beers are now sold in 16 ounce servings. A bucket of four 16 ounce Bud Lights are $17.50, or $20.13 with the 15% tip added.
I once hit $750 on a slot with $.75 in it just walking by. I say save all you can if you have a few people drinking the same beers.
You can still get buckets of 12 oz Coors Light. I don't like the 16 oz aluminum bottle/cans of Bud. I sip instead of slug, and they get warm too fast for me
