There use to be a card (Paywithmoon or something) that I used, you pick the exact amount you need, like 21.21$, get a LN invoice, pay, you get your Visa virtual card loaded with 21.21$, pay, delete everything, rinse and repeat.

But they stopped at some point, maybe it's back now and more blocling, it was US merchant only, with a lot of limitation.

If someone can make such card, worldwide, I'm interested.
