Thinking about dipping my feet in with Serve. Gonna get a GreenCard for free loads at FD/DG. The fee is fine since I don't live in one of the excluded states, it's basically the equivalent of buying a handful of MOs.
1. If I keep low volume low, like around $2-3k most per month, is there any reason to cycle through multiple Serve cards? It seems like there hasn't been much talk of shutdowns since Amex handed over Serve to another company?
2. I don't mind the monthly fee, but does it actually get waived if I balance to zero before each statement cuts? Seems like a great loophole to exploit, but I couldn't find anything on the official Serve page about waived fees.
