Walgreens is branching out. Depending on your state's liquor laws, you may very well be seeing Walgreens' own private label beer, Big Flats 1901.
The attraction, here will be the price. Walgreens plans to sell the suds for no more than $.50 for a can...$3.00 for a six pack and $11.50 for a case of 24.
I like beer. I drink two beers a day. Over the years I have found that expensive beer does not always taste better. I've also found that cheap beer usually tastes worse.
There's a reason why it's cheap!
