Pet Supplies Plus $1 gallon sale
Posting this here, since I know there's a couple in the area. One in Allentown and a smaller one in Bartonsville (Stroudsburg).
Pet Supplies is a much smaller chain, but they seem to run pretty neat stores. Franchised if I remember right.
This one is much the same as the Petco sale: 10,20H,29,55. 40B wasn't listed in the circular. I'm pretty sure they are Aqueon, but if it's an issue for you a phone call would be advisable to confirm.
The first time they ran this a couple of years ago, they included 15G's.
