I find the GSP is only good in very specific situations. Big, bulky packages usually work out a LOT cheaper from the US to here for some reason, however small packages are MUCH more expensive. Maybe it averages out? Who knows. I used GSP twice last year, both times for HUGE boxes, one had about 50 ponies, the other had playsets and ponies, but I live on a one-country continent, and in a capital city, so that's fine.
