If you can, try an actual electronics supply store. I don't know how the pricing is in the US but here Radio Shack or The Source as it was renamed always charges way more for fuses than anywhere else, like $5 for a single fuse where it would normally be $0.50 elsewhere. Of course it depends what stores you have available to you, bigger cities have better stores.
