I'm thinking about getting myself an AMEX Business Gold card to pay all my adspent with. I just discovered you get 4x in points for every dollar you use your card for ads and marketing. Those points you can apparently use for any charges. You can for example use it for travelling and hotels etc. That's so fucking clutch! Ive been paying my ads with my debit because my other credit card has a really low limit but right now I am thinking of getting one. Has anyone experience with that?
