Sellers don't actually "charge" for postage, they price it up and the decision to accept it or not is the buyers'. I always add it to the price of the record and make my decision on total cost. Buying from the US can range from $10.00 and anything up to $28.00. If it's the latter I always challenge it and ask for an explanation, usually they'll come down, I quote the USPS website calculation. UK postage costs are pretty good, perhaps only bettered by Holland and the US. Paying up to about £2.75 for a 1st class signed for (remember there's £50.00 insurance included) isn't extortion and anything over that value should go special delivery at about £5.50 - 7.00.
