I've made several purchases from Germany and the UK.... Just make sure they will ship quickly with insurance and tracking if need be...or else it may end up lost in the mail BTDT...they shipped at no extra cost to me, but my purchase ended up getting here 1.5 months after I bought it.
Nothing really bad to say....if it's off of Ebay....and pay with Paypal...you've got nothing to lose really...you are covered.
I have ordered many things from Germany, and te UK. Most of the time the seller will make the decision on who to ship with. I have had many come through DHL, and most loc postal organizations. Irregardless, most will end up being delivered by USPS.
