As an e-commerce business owner, I put a lot of stuff on credit cards. Inventory, ppc ads, business-ish travel, and business-ish meals. So I finally gave in to this credit card hacking craze. I was a little skeptical about how long a credit card company could give away all these points/dollars/miles, but I finally just decided to get in the game. I still think the credit card industry is ripe for a disruption (businesses pay a lot to take credit cards), but meanwhile I’ll take what I can.
