I will now but I don't think it'll do much in the grand scheme of things.

Even if you bought 1 bag every day for a year that'll be $18.25. Most people won't care enough to reuse bags and will continue doing business as usual pre-tax.

Then of course, there's the ~7.4 billion other people on Earth who never even heard of a plastic bag tax so their habits won't change either.

I would rather see them just stop manufacturing plastic bags and also make them illegal. If their goal is to cut down on people using them that would be the way to do it. Instead, they tax it to an amount where they are hoping more than enough people won't care enough, so they can profit off laziness while they care nothing about the environment.

At least when I was in the States a few month ago, the bags I got at the grocery store where of really terrible quality (this was at Publix). They barely made from the store to my apartment without falling apart. Reusing them was completely out of the question. Most bags you get in most places I've been in Europe are much sturdier and can easily be reused a dozen times.
