I also use mine for the small trash cans around my house but they definitely add up. I end up with way more than I can use so I constantly have a bag full of bags! Recently I bought these bags on Amazon and they're great because unlike many of the reusable shopping bags (which I find bulky), these fold up so small, can be washed, the handles are long, etc. They hold much more than the grocery store plastic bags too. And, they can be used for more than just a quick walk to the grocery store. For 6 bags, the price is good. These are just one example but there are many on Amazon nowadays as more and more places are stopping the use of plastic bags:I could never figure out the nonuse of plastic shopping bags. I use my bags for trash. If you don't use your grocery bags for trash do you buy plastic bags for trash?
Really, I like paper but I have to walk to do most of my shopping. Carrying reusable bags all over is a bit of a hassle. I use a little shopping cart if I'm going to buy a lot but for a quick run with my 2 dogs in tow a plastic bag with handles is good.
And what do people use for dog poo bags? I use the small bags from the Colmado for that.
Reusable bags
Doesn't help with the dog poop issue but I do feel like I'm doing my part, albeit small, to "save the planet" with these bags
