i think you can open a dispute if the seller is not co-operating. it is the same as him refusing to sell you the item.

I am familiar with that seller and have dealt with him in the past with no problems. He is the same seller that STSG "claimed" to have problems with although I still remain quite skeptical about that at best.

Anyway, one thing that could be happening is that your emails, even though they are going through Ebay, might in fact be getting hung up in his spam filter, because it happens to me all the time(especially with my Italian buyers) for whatever reason.  Try logging into the US side www.Ebay.com and then shoot a message from there.  If that doesn't work and you are still getting ignored after a few days, then I'd defintely go through reporting him through the Ebay route.  You also might want to check your own messages in My Ebay to see if perhaps his emails back to you are getting hung up in your own spam filter.

On a side note and just curious, C how are you planning to pay this guy since he doesn't accept Paypal?

Finally, the matter appears to have been solved. At least, the seller contacted me with the invoice. Now I hope that the rest of the transaction goes well.
