They're a very good shop, AFAIK.
Shipping on bulky items (Honjo fenders!) is likely to be very pricey.
The "customs" thing is a total lottery. Some US mail companies seem to get through (I was lucky recently with USPS).
Others always seem to get "intercepted"on the UK side by bandits who will charge you a fee for completing the customs clearance forms (even if all paperwork is already in order) and hold your parcel for ransom until their "fee" is paid.
They give Somali pirates a bad name.
Email VO to see what courier they use and what they advise.
And try On-One or Fresh Tripe, as OO sell Honjo, Soyo, Nitto etc. and FT now stock some of the VO range in the UK.
Best I can suggest - Sorry.
