Target sells a 50 pk for $10.39, not Arm & Hammer but they work well. 24"x23", They come in a blue and white pkg - I forget the name. It might be their own brand.
Walmart sells them cheap too.
I was thinking about the washable kind, but I haven't heard anything about those - not sure I want to wash pee pads everyday. I got enough laundry to do. UGH!
