I probably should have researched the GSP before I listed the razor I have up at the moment, but I opted in this time because I'm tired of all the potential buyers I get wanting me to under-declare on customs forms, mark items as "gifts", and other semi-nefarious subterfuges. I guess the deal is that I don't make the rules on eBay, I don't make the rules on the SRP classifieds, and I don't make the rules at PayPal--- so I use the selling tools and try to stick to the rules because my privileges at all the aforementioned sites are important to me.
