Good for you Chris,
I stopped shipping anything into the UK from the states years ago,shipping costs ,plus import duty (11% ) plus VAT(20%) plus collection fee (£11) etc,plus a fixed (read poor) exchange rate charged by the domestic Mail carrier, in total can add well over 40% to the original price paid,simply prohibitive.
Post Brexit we are now seeing EU countries stopping sending product into the UK because the additional paperwork now required is simply not worth the grief,especially on low value shipments,plus VAT at 20% is being charged and collected on your doorstep when your parcel arrives.
I’ll stick to shopping while on holiday.
