The closest thing I used to pay for was Android games, but only a few euros at a time. Now it's big games when they have an offer.
I'd have to be self-employed or have my employer pay for it if I needed a small web tool. It does fit more into the "need" category than "want", doesn't it? That is, IF you need it and that's a big IF.
Why is it a big IF? If you need it for your job you pay for it. I would hate it to have employees wasting their time coding something by themselves that we could just buy for a few bucks.
