Today I discovered that the $25 credit card cash rebate has been deposited to my ShareBuilder brokerage account. For record, it has been almost three months after I started to use ShareBuilder Visa Platinum Card, and during the period I spent around $2,600 with the card.
My near future credit card preference will still be the MBNA MasterCard, which I have accumulated around 17,000 points. Once I achieved 20,000 points on that card I will switch to use the ShareBuilder for quicker cash rebate. (MBNA MasterCard offers $200 cash back on 20,000 points, but only $40 on 5,000 points.)
