The HD I went to surprisingly had around 10. I picked up 3, 1 for myself and the others as gifts. My only complaint is that the pockets on the side of the smaller bags don't fit very much.

I stopped by home depot and found this 3 bag combo for $15.
Husky 3 Bag Combo-82070N13 at The Home Depot

I was looking to get the 2 bag combo from walmart but I think this might be a better deal.
