As someone you recently bought a empeg via this board, and living in Africa, I wouldn't trust USPS. Fedex/Ups/dhl are the way to go. Also, it's resonably cheap to ship from the US to europe.

Paypal or similiar is probably easiest for most people if you won't accept credit cards (but why wouldn't you)?

As for customs they can be real nasty (here in South Africa they charge on everything!). My 1st empeg I got from carplayer.com, they put the taxable amount as $89 but the invoice had the correct price.

Also (at least in SA) , putting it down as 'car spares' seems to be good.
