Not sure what he is worth, Peter - I got him a long time ago and can't even remember what I would have paid but likely not an awful lot. I did see him pictured in one book - "Teddy Bears" by Sue Pearon and Dottie Ayers from 1995, but that bear was 20" (mine is 13"). It was listed as being worth $300 - $600 back then, but it didn't say anything about whether it was rare or not.
I was caught with this too - bidding and not noticing the GSP. I've contacted a LOT of US sellers about it now before bidding on things and MOST of them had no idea what it was all about or even that they had it on their listing. This is what bugs me most - ebay is being so underhanded about it - UNLESS the US seller notices it and UNCHECKS the box for it, their item will be listed with GSP for international sales. If they want to offer this so called "service" why wouldn't it be a case of the seller CHOOSING to add it to their listing, NOT having to notice it, or remember, to remove it! And as far as "service" - WHY would anyone choose to pay double shipping - as if shipping costs haven't gone sky high as is! - for their purchase to be shipped from the seller to a central US location and then that company in turn to ship it to the buyer! And as you said, Canada Post so often lets lower priced (and even some higher priced) things just go through so more often than not there are NO extra charges on normal parcels. A further problem for me is that I live in the country and only have a post office box so if the GSP company ships by courier then I cannot get delivery.
