As I have British family we have a UK bank account so we watch exchange rates. The Brexit vote has pushed the £ to about 1.3 $ per £. They also pushed the VAT (sales tax) rate to 20% a few years ago, but we don’t pay that on export deals.
This means that UK stuff is about 20% cheaper this summer. A £1000 item is £834 pre-vat or about $1090. Shipping seems to run £100 or so.
I found a couple of locos, a Regner and an Accucraft that I think are discontinued and sold out here. Good deals!
