Good old Ebay - ripping people off , if your outside the US - in effect with the GSP you pay twice for shipping - the seller posts to the Ebay shipping facility ( you pay for that ) and then you again for it to be shipped from there
And for the life of me - why is the cost so erratic - same item and you get 100 different prices - from the correct to the insane and everything in between !!
US sellers are the laziest and just throw a random weight - come Ebay get it right **bleep** , it's 2017 and the postage stuff ups are from the stone age
