I have three and I am not looking for any more. I have two Visas and one American Express. One of the Visa credit cards I would love to close because the interest is really high, but it was my first card, oldest account, never missed a payment or late by even a day so I'm keeping it open. I may call them and try to negotiate a lower interest rate. I have friends who honestly have more than one dozen credit cards, but they all have low limits, like $300, so I don't think it's very smart on their part.
