This is more of a general CC question than a hoarding question but I think you guys will be able to help. My wife and I have a bunch of credit cards that we've accumulated over the years but we only use a couple each month. We use a specific card for groceries, a specific card for target, a specific card for online purchases, and a specific card for everything else. We've had travel cards in the past and other reward cards that we don't use at this time.
But we want to simplify by getting rid of old cards that we no longer use and the question is what's the best way to do that without harming the credit score. She has a credit score of 830+ and mine is 780+. Is it OK to get rid of ~10 cards at once? Or would it be better to spread it out over time and slowly reduce the number of cards we have. And if we cut down from 20 to 10 cards (or lower), would that drastically change our credit score? Or, should we be looking at the available credit amount and not reducing that too quickly (or by too much)?
