I'm willing to eschew disposable shopping bags -- except for the few plastic ones that I reuse as liners in bathroom trash cans, or the big paper bags that we use in the truck for trash.
What I would prefer is the old-style European expanding string bag like, perhaps, these. As a retail clerk in the past, I'd prefer something that makes the management more comfortable than the canvas and other opaque bags that can conceal shoplifting.
I also don't want to pay a premium price for something that's "eco-friendly," or pay shipping for something that should come at the dollar store for about four bucks.
(Thanks, kitchen hand.)
