Sharing Accounts to Maximize Cash Back and Interest Earnings
May 4th, 2008
The other day I posted a comment about how my sister and I share an AMEX Cash Back credit card on Kevin’s post $327 in AMEX Cash Back Thus Far at No Debt Plan and he emailed me to ask out of curiosity why I share an account with my sister because it sounds so risky. What if one of us decided to go on a shopping spree and screwed things up for the other person?
I emailed him back explaining our logic, and while it may be unconventional, for us it is a convention we have practiced with success for many years. Ever since our high school days when our parents would give each of us pocket money for lunch, the bus, pay phones, etc. we have always regarded our money as literally “our money.” When one of us didn’t have any cash and wanted to buy a drink or snack at school, we would just ask the other person for some. And to the shock of many of our friends, we would just give each other the money. We never had a distinction of “my money” and “your money”.
Perhaps this had to do with our always having been somewhat unconventional people, even as kids. While our friends went to the mall, movies or shopping, we preferred to go to the library, karate class, or stay at home and read or play with our pets (we had dogs, cats, 20-30 rabbits, guinea pigs, birds, fish, mice, etc.). So for us, money was never really a means for pleasure but living - taking the bus home from school, buying lunch or an occasional snack or buying pet supplies. Because we didn’t habitually spend money, our parents didn’t put us on allowances and would just give us money when we needed it. (This could explain why we still live on a No-Budget System.)

In recent months, the subject of “too many credit cards” has frequently arisen on blogs and forums. I have even seen a post title saying that closing a credit card will immediately boost your credit score by 10 points. I don’t know if this is true; a quick search on Google didn’t turn up any substantiating information.
