If you are going to use USPS it is also a good idea to use AIR MAIL. The cost is marginally more (25%) and the item gets here in about a week or so. I've had ground items take up to six weeks.
The brokerage fees at UPS are just plain silly. Something that might cost $50 in fees from UPS is a flat $6 charge from USPS.
