I have placed bids on several powerbooks on eBay. However I am reluctant to send money first. The people are in Canada. I am aware that certain shipping companies like Fedex have a program where they deliver the package and hand it over only under the condition that the recipiant hands over a certain amount of money which is in turn given back to the sender. I have used this method of transfer before. But does anyone know if Fedex can actually check to make sure that what is in the package is an actual working computer system? Is there any service any major shipping company offers that would actually check that there is a functioning computer system in the package...or at least let you examine the package contents before handing over the money?
