Hey /jp/ - I got a question that doesn't need a new thread.
I was considering getting a "pre-paid credit/debit card" - I'm looking at one that uses VISA as my Credit Card is Visa. I'm kind of worried about some of the hentai I've purchased in the past... So instead of continuing to use my Credit Card. I figured i'd use a pre-paid instead.
Do any of you know or use pre-paid debit/credit cards to purchase things online?
I mostly buy some from 'dlsite' and random purchases from amazon and other types of website. Will I be able too? Treat it like a credit card, though its one I put money into myself?
