Well, my husband got the consumer card first and got the extra 15,000 points b/c we had a big purchase to make at that time. Then a little while ago, he and I both got the business card and I picked up the consumer card but we're not spending enough on them to get the 15,000 bonus points again. As it stands right now, we've got about 78,000 points (we're still waiting on some sign up bonuses that have yet to appear on our accounts). I would like to eventually, somehow, get 180,000 points total.
We haven't tried churning any of the business cards yet. I'm just wondering how many times (if any) they'll let us get away with it...
