I think one thing that may be misunderstood is that many of these chains have "reusable" bags that are very hefty plastic bags but are not the very durable reusable bags made of cloth/canvas or materials, the ones which are basically tote bags. I think the people who buy these more expensive bags tend to use them more than 3 times. But the ones that cost 99 cents at the register end up getting repurchased everytime someone forgets their bags. It took me a while to get into the habit and I know I have about 60 of those accumulated from the last 10 years of occasionally forgetting them. The bags I do reuse tend to get used many many times, but the rest might get used just once, because I already have a pile of them. If i remember my bags, I take the nice ones. If I forget, I have to buy new hefty "reusable" bags.
