But never the card. Reading such user horror stories, or Terms & Conditions, makes me turn around and never come back.
Not to say that Paypal won't screw you over, just that it doesn't do so all the time.
Relatively few monthly statements on it make anything funny stand out, and it's easy to just report/cancel the card.
Some banks have web/mobile banking where you can restrict actions/limits/transactions, so it's a good option too.
Others have virtual cards for this purpose, but these are not offered in a lot of countries (revolut, privacy, yandex money, etc).
You apply for the card online and get it in the post.
