One of my clients had special bags made up that he had designed for Christmas as gifts. I was the happy recipient of three of them. I bought a slightly larger one from Petco.

They are so much easier to handle than plastic bags and your groceries don't fall out as they do in plastic bags when you are driving.

When I get home I unload them - then put them right by the front door so next time I need to go out - I put them back in the car.

I am hoping that they soon ban the plastic bags but I do use the ones that I get for kitty litter. The only problem is that some of the bags are so flimsy that they won't hold the litter.
