I have been using the cloth bags for over 20 years. At first I only used them for groceries, but when all the others stores started selling them I started using them everywhere. I like the original canvas ones I got 20 years ago from Almacs which is now out of business. I switched to the flat bottom ones but they aren't as durable. I use the canvas ones when I need to carry heavy stuff. I keep most of them in my car trunk, but have a few in hubby's car in case we go in his car. I got one of those bottle separators at Trader Joe's so I could carry water bottles with me to bowling. I should throw that in my trunk too for when I buy glass bottles...never thought of that.
I'm working on hubby to get the paper sacs when he shops so I can use them for newspaper recycling. He's a tough sell. At least he's starting to refuse a bag when it's only one item. Small victories, small victories.
