What do you scoop cat litter into?

I've always doubled up 2 grocery bags and used that. I mostly just use reusable bags for groceries now, so I'm running out of plastic bags.

What else do you use? It's not practical for me to scoop it into the trash can because it takes us several days to fill a trash bag with trash and I don't want dirty litter sitting in the house for days. I like to scoop and take it straight outside to the big trash can.
