I check the AMEX preapproved offers site regularly. About 4 times per month. About 2 months ago I noticed I finally received pre approved offers. I didnt apply. The next day was the 1st of the month and when I went to check again...no more offers.
Yesterday he 30th I checked and no offers. Today, the 1st, I had new offers.
It seems that AMEX preapproved offers may "reset" on the first so if youre thinking about getting an amex now might be the time to try.
DPs - My EX FICO at my first prequal was 679. I was repeatedly given no offers with scores of 699 to 732. My score on todays prequal was 705. Age of oldest open acct is 6 months on EX. Oldest acct is 7yrs.
