Finding Ross' Deli was a shock. How did I live in Lakewood this long and NOT know I could buy my favorite beers by the growler? Beyond that, a growler usually has a savings of 10-20% off the price of a 6-pack!
You do have to pay to rent the growler from them, I think it was a couple bucks. However, once you've got one they'll exchange it for a clean one each time you return for a refill. This is a great way to save on seasonal specialty brews that can get expensive.
They also have a wide variety of bottles and wine if memory serves. (Which it rarely does, but who cares! GROWLERS!)
