I couldn't find the answer to this question although I'm sure it's been discussed here:
If I got an Amex signup offer in the mail and apply after the expiration date on the letter, can I still get the bonus indicated in the offer if I use the offer code?
If not, what is the best offer currently available for Amex platinum or Gold business or personal? I have 75k welcome offer but need to spend 15k in 3 months?
Thank you for any help
