Hate to say it, but you missed the golden days of being able to purchase Vanilla Reloads at CVS with a credit card and load them to a Bluebird account, form which you could easily pay the credit card bill. There are other methods, though, like buying pre-paid debit cards with a PIN number from grocery stores and loading them to Bluebird.
But this isn't a manufactured spending forum, so I'd recommend that you check out the forum for it here on FT. A literal gold mine of information, that place is!
If you're going to get into manufactured spending, just BE CAREFUL.
