This is all new to me. The extent of it I mean. We've gotten plenty of free flights, and sign up bonuses, but had no idea there was so much else out there! How did you get started? Are there websites to check to learn the ins and outs? I don't think I could ever achieve your expertise, but I would very much like to improve my knowledge.
Also, I was wondering if most people pay off their many credit cards each month? If not, that would negate much of the gain I would suppose. We only have a couple of credit cards by choice and use them very specifically and pay them off each month. We are debt free including no mortgage and tend to pay cash for everything. HOWEVER....we would be disciplined enough to work the "hacking" i we understood it more clearly.
This has been quite an eye opener!
