It may be that the $53 or whatever is a flat rate automatically billed, but they'll refund the difference to actual costs. See
this page.
But then there's
Old Glory UK whose
FAQ says
Q. What about the Fantasy and Horror ranges that are on the OLD GLORY US website I can't find them in the UK.
A. We do carry the Blue Moon Manufacturing range of Fantasy and Horror models – though not all of them. There are several ranges that appear on the US site Old Glory 25s that we do not carry as stock simply due to lack of space and demand. However we CAN ORDER THEM FOR YOU it simply takes a little time. The procedure is simple, phone or email us your order with your payment details and shipping address. We will then give you a UK price including shipping from here to you. Once we agree then we will add your “special order” to our next stock order and then ship it to you once it arrives from the USA. This can take a few weeks but you will get your order.
There will be VAT and shipping from the UK (see the same FAQ), but it's probably better than the US option.
Or you can hope that some Old Glory Army member wants to reduce his lead pile and ship at cost.
