Hello Beer Friends Nation! Every once in a while the Beer Friends like to step out from our craft beer world and try something... well... from Walgreens. Walgreens Big Flats 1901 Lager is a pale ale that you can find at participating stores for 3 dollars. That's right, 3 bucks. However, you pay for what you get (at least that's what my dad always told me...) Cheap beer! Walgreens! 1901!
