He said he needs a case- that is PA law
No this isn't quite it, the law is that an independent store or bar cannot sell more than a 6 pack at a time. So there are lots of 6 pack stores around, but the price is higher and they usually have a side line in the store like sandwiches. Usually sell 40's as well. These stores are open later and longer and usually 7 days a week.
The other side is larger supply stores, that have shorter hours (as in close @ 6pm) and are required to be closed one day a week (most choose monday so to be open for football sunday) and they sell cases and kegs. Heck some even deliver the kegs if you want, many times we got kegs deliverd to the frat house, but it was cheaper to pick up so did that when we had a truck available.
I lived in eastern PA for 5 years and Western PA for another 5, but have been in AZ now for 10 so things may have changed a bit, but I know they have not changed to much as I have a friend that runs a bar down in the South Side of Pitt, always bitches that he can't get booze cheaper than the average person so is hard to make a ton, mixed drinks are more profitable than beer due to this. In PA the bars have to buy from the same supplier for cases/kegs at the same price as everyone else, it is state regulated.
When i moved to AZ it was a shock to buy beer in groceries and gas stations, but then i suddenly realized that it is all BMC and more expensive than the Micro cases in PA, until recently you didn't even see 24's regularly usually 18 pack bottles and 30 pack cans, so it is a trade off. You have to find some specialty shops for a good selection in Phx, although more and more stores are carrying micros as the years roll by. More available in AZ but 40% to 100% more expensive, cheaper in PA but have to get to store by 6pm to get it...
So to the OP it is hard for us to say as pricing and availabilty changes from state to state greatly due to patchwork laws. But I do remember Saranac was a resaonable NY Micro, as well as Yuengling of course, of course there always is Keystone or Milwalkee's Best
PS I still miss Yeungling, can get IC out here, but that is prety much BMC.
