Are there extra charges for shipping when buying off eBay when using ups?

Each seller determines what his shipping will cost the buyer. UPS is more expensive. When I was a seller I used Priority Mail service USPS boxes are free. You should be careful, some sellers try to make money from the shipping. If you are paying more that $5.00 to $6.00 for shipping (for an item one pound or under) you are getting ripped off. Small items can be shipped for $4.00.
