I have 16 inquiries on TU, 11 inquiries on Experian, and 6 inquries on EQ so I definitely don't need to do any more applications. However, is it is a bad thing for me to add accounts by AU, or for example shopping cart trick to increase my credit limits thereby increasing my utilization. By the way my AAOA is a average of 8.2 years on TU, EXP, and EQ.
It is up to you. I would personally add a solid AU account before doing shopping cart tricks. IMO unless you shop at one of the stores religiously it is a waste of a hit to you AAoA. I understand that it is a SP, but you probably won't gain a whole lot of padding on your util as most CL's are only a few hundred bucks.
IMO, wait for your scores to rise up and apply for a card you want. Doing the shopping cart trick is cool and all at the time, but you will most likely regret it later.
You're right. I think for me its best to just continue my gardening and wait it out. I've managed to get 2 paid collections deleted from my credit reports this week, so the work continues to pay off.
I think that would be the best bet. Continue cleaning up your reports and you will be happy in the long rung. Congrats on your recent success.
