I have various canvas bags I've acquired over the years that I use for groceries - including 10 yr old Safeway bags. But the bag I use the most is a little bag, "lunch" sized, that I got at a quilt seminar - not made in a Chinese sweatshop, but a quilt guild "sweat shop" in preparation for the seminar. The ladies made about 150 of the completely lined little bags to hold our Welcome goodies. I use it to bring my lunch to work, mail, and all those odd small bits that don't fit in my purse that I only need to take somewhere occasionally.

As for plastic store bags - I do still use them - for used kitty litter. Maybe if I had a larger yard, and could build a bigger compost pile, AND get the kitties used to a compostable variety of kitty litter, we could eliminate the need to dispose of their waste. But there you have it, I admit I send poo to the dump on a regular basis. But my weekly garbage pile is still much smaller than my neighbors.

On a side note - while I was choosing something in WF, and commenting that the variety I used to buy was no longer available to an empolyeee nearby - he said that they had similar sauce available, right here in a glass jar. Told him, maybe so, but I can't recycle the glass jar, and I can recycle cans. Glass recycling isn't available in my area. If the sauces taste about the same, then I'll choose once that comes in a container that I can recycle.
I don't know if my comment made a difference, but canned variety is back on the shelves.
