Join the very, very long line of Canadian eBayers who hate and despise this program and want nothing to do with it.
Unfortunately eBay refuses to give us a way to filter out items being shipped with its pet program which means that the "Customs services and international tracking provided" blurb is all we have to avoid them. When you see that, don't click on the link, just keep searching.
I try to look at it the positive way: I think of all the money the GSP has saved me because of all the items I did not buy from the US. The money that used to go to US sellers is now being spent here in Canada instead.
