Paul, you can't really blame PG Music for UK import tax and VAT. I suppose if it didn't exist we would all be buying loads of stuff from abroad which wouldn't help our economy.
I've found in the past that if goods are shipped with the likes of Fedex they are very keen on collecting the duty but if shipped through the regular mail so that Royal Mail make the delivery they often don't bother to collect it. Not only that but they are just as quick.
