I have bought 2 buck knives with stag handles from the copperandclad account on the big auction site because that way they do ship internationally (they don't do so from their website, sadly. I'm sure there is some sort of bureaucratic reason for that, for which the auction site is the work-around). I have to admit I was hesitant the first time I ordered, but I decided to give it a try anyway. I'm glad I did.
Both times the product, service and speed were exemplary (insofar as you don't have unrealistic expectations about the speed of your postal service, but that is something neither party can influence). Or as they tend to say over there: 'GREAT SELLER FAST SHIPPING AAAAAAA+++++++++++++++ etc. etc.'
They can definitely look foward to my return business as I'm still eying a buck 105 in cocobolo which I can't get over here. They're great for the more exotic Buck knives which aren't easily available in the Netherlands.
If they ever start shipping internationally from their website and accepting paypal then I'd probably prefer order via their website, though.
Just my 2 cents.
