Other than Audiogon.....if your using 3rd party shipping services like THE UPS STORE....they can charge you whatever they want. They are NOT connected to UPS at all...or the actual UPS rates.
Whenever possible actually go to a UPS or FEDEX store (FEDEX OFFICE) that is owned by the actual company. Also sign up for a Business Account to save an additional %. Think I save 12% thru FEDEX on Domestic packages and up to 80% off on Foreign Packages using their Smart Rate program (Which you can only get by calling a 1-800 number that is not affiliated with their stores)
