No worries. Smaller huh? PS3 sized ones maybe? It all depends on the dimensions. I believe the maximum total dimensions for First Class Mail is 36". That includes height, width, and depth. Once the package goes over that total, it must be Priority Mail, which is why the price would be $45ish.

He may need to check his measurements; perhaps he's just assuming it will need to go Priority? Otherwise he may only ship Priority, since it comes with insurance up to a certain amount. First Class doesn't.
