:: Yeah, exchange rates are what I was talking about when
:: I said "UK import shipping fees"
Does the US have actual import fees, though? When I was living in Iceland, EVERY commercial item was taxable, so a five quid DVD (including postage) would actually end up costing you about ?10.35 once the fees were taken into account (24.5 per cent VAT, plus 10 per cent "you got it from overseas, you bastard" charge, but a five quid handling fee). In the UK, you have this to a lesser degree?VAT on items and postage are chargeable on any commercial item that costs ?18 or over and any gift that's worth ?36 or over.
As for eBay fees, I've found people in the US to be terribly greedy, too, largely due to their insistence on using Fed-Ex rather than standard postal services. It's not unheard of for US sellers to charge $12 to ship a CD to the UK, for example.
The main "rip off" charge from my point of view, when sending stuff overseas, is the signed-for rate, which jumps from 66p inside the UK to a wallet-busting ?3.30 overseas. Unsurprisingly, most people aren't willing to pay it, but then if the package gets lost, it suddenly becomes their problem, not mine.
