From my understanding, having too many CC accounts open (more than five) can negitavely affect your credit score, even if they have a zero balance.
The theory is that it is possible for you to max all of those cards out if you so chose, and so all of your open credit is taken into consideration when determining your score.
It is best to have no less than three CC, and no more than five. At least one of them should have a high credit limit (say, $10,000 USD) and the rest can be any limit at all.
Also, closing CC negatively affects your score. Not by much, only a few points.
If I were you, I would not open up an Overstock.com card. But then again, you already made your big investment, a house (unlike me). So, if you want to save on your Overstock purchase, it won't be
that big of a deal.
