Is my shipping figure wrong?

Question

Sometimes when I list an item, the shipping figure almost always seems low to me.

Example:

I have a Bass Guitar listed and it shows approx. $12 shipping from here in Florida. When buyers see it, is it different to them, say someone in Idaho going to see a more reasonable amount? USPS is the shipper in this example.

Does eBay get THAT good a discount buying the label from USPS? I don't want to get shafted for extra shipping cost!!
