Don't think there is a restocking fee... but I'm not 100%. If it's going back to store, I'd call and ask first, or same with if you are returning to Apple online.
Not to be a jerk, but I don't understand questions like this. Wouldn't it just be faster to call the retailer where you bought your Macbook rather than to post on here and hope that someone responds to you?
