Is this really a problem? Too many credit cards make your wallet uncomfortably large? Let's get back to solving problems that matter. I can't believe we have three companies on the front page today reducing the number of credit cards in your wallet.
My kingdom for a solution that gets me down to one card.
If I'm going to be somewhere where I might need a business CC or debit card then they're temporarily added. Otherwise I store all my CC info in 1password anyway which I can access on my phone.
My problem is the 15 loyalty cards I'd need to carry to get my free mocha/chicken/subway/points/etc/etc, give me an amalgamation of that shit and I'll love you for ever.

Things like mint hasn't worked out for me so I do it this way, very easy at the end of the month to see where I've moved off the budget to adjust.
I'd like one card and a thinner wallet.
