Yes, I use the Buyee service to buy from the auction site - works fine but they declare full shipping value so for anything over $25, I generally expect to get charged VAT @ 20% plus a handling fee once it arrives in England so often there's no saving on using the regular providers who charge more but help avoid the fees.
I actually bought 2 copies of the box set talked about above, separately, and they both came in under the threshold for VAT/fees so happy days - this is when they were $25.
Sometimes there are items sold at big discounts which even with the VAT and fees paid are way way cheaper than the usual suppliers.
Also Buyee offer registered airmail which is half the cost of EMS for small orders so this is a saving over some other suppliers and Japan Post is excellent.
