credit rating and department store credit cards

[cash78mere]

i have a really great credit score for someone my age. but i want it to be even higher.

does it really raise your credit score if you close out credit cards that you never or rarely use (like gap, j crew, etc)? i have about 3 or 4 cards that i just never use, but keep them just in case. i'm willing to get rid of them if they will actually imjpact my credit rating in a positive way.


help please!!!
