Maybe it's regional, but Aldi by me definitely has plastic bags. They're fairly sturdy as well— I've definitely gotten my 10¢ worth

You should stop that.

I assume you're vegan, you don't own a car, you never travel by airplane, you don't use heating or air conditioning, you only take cold showers, you wear your clothes until they're worn out beyond repair, etc. When somebody takes environmentalism that seriously, it might actually make sense to worry about a few grams of plastic.

Well:

1. Plastic bags often don’t really get destroyed, but get shipped to poor countries and land in the ocean. 2. Paper bags or boxes do the job as well, unless you are driving home your stuff through a long walk under rain or bike. But pedestrians and bikers usually have enough bag capacity with them.

I’m only using plastic bags every couple months, because I know keep bags and boxes in my car trunk. Easy, 0 impact for me.

Or at least bring last trip's plastic bags into the store with you.

I use them for garbage - I don’t have any left to reuse.

Well, the problem with plastic bags is that when I need them, I usually don't have the last trip ones. If I prepare for my shopping, I don't take the plastic bags because I prefer my cloth bag.
