Some Ebay sellers from any country never learn !!!,if they have messed up calculating the postage costs they should make up the difference for you.
Two reasons for this : 1.It is their fault and should never blame or deceive the buyer.
2.If they have any common sense they say sorry my fault and it's in the post for you.For a few extra dollars to them they get
in return positive feedback and a customer who will buy from them again because they are honest and reliable,which in
lay mans terms is what Ebay buyers want,it's not hard really.
I know this because i have made some miscalculations on postage and i have paid the extra because it was my fault not the buyer.
My advice for your pride is F*** them off and report them and don't pay anything,it will cost them in listing fees so they will lose out anyway.
I am sure you will find another item of equal quality and possibly a better price with a seller who is more reputable,i have bought records from
the states without any trouble at all,you have just been unlucky this time,the vast majority are fine.
