Yes,well. I bought a couple of Runbaken magnetos from a guy in Oz.I paid a good price for them,well he thought it was good !!!
the problem was that as it was insured and tracked post,the p&p was quite expensive,and he put the total price,including p&p on the customs declaration form.Of course our friends at Border Force seized on that figure and Duty and VAT me for another £84.00. i have appealed but I doubt if I can overcome ingrained bureaucracy.
Perhaps only the higher value parcels get clobbered, because there are hundreds of thousands of items coming into the country every day, and they can’t cope with all of it, so just target items above a certain declared value ?
I bought a part for a bevel Ducati from California for ~£600 and got stiffed for about £120 duties. Previously bought much lower cost items and had no such issue – I’ve been told that there is a lower threshold below which C&E don’t bother, but I don’t know where that threshold is.
