I've got 4 cards: Citi MC, Citi Visa, Citi Amex and Amex SPG.
The Citi MC is my long term card and the Amex SPG is going to be my go to card from now on. Do you guys recommend keeping your "primary" CC out of this game? I know that it hasn't happened yet to anyone here but I'd hate to have my primary card cancelled for misuse or something. Or should I just start buying with all 4 cards?
Second, should I open a separate bank account at another bank other then my primary so that I don't have to ever worry about screwing up the relationship with my primary bank?
Third, not so much related to $1 coins but hopefully you guys can help. Can I add myself as an authorized user on any of the above CCs? It's just me right now so I don't have any legitimate users to add but would like too if I could add myself.
Thanks.
