Whenever you want, you can remove them. They don't really give you a "bad score", iinm (credit age matters more than AAoA), but can count against you as new accounts. It won't be a problem many years down the line; by that time, they'll be mature accounts boosting your credit score. Any possible problems are in the shorter term.
There's no such thing as business PRG. If you mean BRG, then yes, there is a thread dedicated to selling amex codes.
Thanks for that. Just to clarify:
1. I'll only need to do it once per CB?
2. I can add myself 10 times online with the same info and Amex won't think it's duplicate requests? And the CBs won't think it's fishy that 10 AU duplicates?
3. Do I tell the CBs all 10 AUs are duplicates of the primary card and they should remove all the AUs or that 9 are duplicates of one AU?
Sorry about all these Qs. New to the game
Yes it's the Business Gold Rewards for 75k is that an offer code being sold?
