So I thought I'd post an update.
Remember this all came about when Sears cancelled my cc after 2 years of inactivity causing my credit score to drop from 741 to 731 and that really upset me as I wanted it higher.
So I happened to see an ad on TV as I FF through the ads on the DVR. Much to my surprise BOA is offering a cash back credit card with 3% on gas, 2% on groceries and 1% on everything else. My sister has this but I was unable to find it maybe a year ago. So I went to the site and applied.
At the same time I asked for my 1.5% cash back cc to increase my limit from $10k to $15k and they refused me!
I was shocked as I have an excellent history but ...
So I found out today that I got the VISA signature cc with the 3/2/1% cash back. I'll use this one for groceries and gas, the other card with 1.5% back for other stuff.
I started to get emails from Credit Karma and my original cc bank about a change in my credit score. Ut oh! Much to my surprise my Trans Union score just went up from 731 to 750 and the Experian went to 785!
So this was a failure initially when I was refused the credit limit increase but now has worked out very well. Not only did my credit score increase but I have a better cash back card for gas and groceries. This card has some limitations like the 3/2/1 applied to the 1st $1500 per quarter but I'm never going to buy that much gas and groceries in 6 months much less 3.
