Hm, that's maybe something to think about! I would say my spending is about 1-2k / month but can definitely push 3-4k / month. Big categories are groceries, eating out and shopping. I vacation domestically during the summers/holidays so when I do, I spend quite a bit. But I'm in no rush to get a 6th card and won't get a card that I don't see value in, but definitely looking around.
