Want to buy smaller quantities at distributors and larger quantities at take-out shops?
PA Senate Bill 674, which proposes allowing beer distributors to sell 12-packs, and taverns to sell up to 3 six-packs. Pathetically incremental, I know, but it's a start. Please e-mail your PA Senator (you can easily do it here) and ask them to vote for Senate Bill 674. This bill will not affect consumption (it lets you buy LESS beer), it will not allow supermarket sales, it will not affect underage drinking. It is a convenience for citizens, that's all.
Here is a Post-Gazette article on the bill as well as a link from which you can write your legislators.
