James,
No, not implying you are weak at all. I just have not found (with the exception of heavy items or expensive items) "import" to be an issue, in either direction. In fact, in both directions between EU/UK and here, NEVER have I had to pay any import or export duties or taxes, on again, smaller things that go mostly by post. Generally they are delivered quickly and efficiently. I sent out hundreds of the Pagoda Style books--a non trivial shipping cost, and a value of USD $75 each, and most were delivered to their destination w/o any taxes or fees. I know I got the whole lot of 500 delivered by truck to me from the printer in Canada w/o any hassle either. I've bought some car parts new and used from overseas shippers, and all came in quickly w/o any paperwork or taxes.
Now, when you get to the $2,500 range US, a different set of rules kicks in. Also, if you use someone like DHL or Fedex or UPS and have something going "freight" (lower cost shipping) versus "express" (expensive quick shipment) you frequently have to deal with your own freight forwarder, or import agent or the like. That's a pain, if only for the fact that they have a "minimum" service fee you have to deal with, and some paperwork, too.
I would suspect a set of dash wood can be sent from the USA pretty easily, and received the same way in UK. I would just ask that the seller/shipper in the USA (for you or your friend's benefit) use the US Postal Service, and probably choose "International Priority Mail" for the least amount of hassle.
I'd be happy to intercede on your behalf if the seller/shipper doesn't want to do international; there is some paperwork they have to do but it's all online and seconds to fill out if you know what you are doing. I've done it regularly and would be happy to help. PM me.
