My mom is going to add me as an AU to her cc. $15,000 @ less than 20% utilization with over 15 yrs. Does anybody have a guess as to how much my scores might go up? I don't have any cc's and I got an offer that made me want to laugh and cry at the same time. $95.00 proceesing fee, $89.00 yearly fee, $6.00 monthly fee and it only gets worse from there. I'd have $72 dollars left out of $250 credit line. TIA
