Ok, the buyer has sent the coins to Graet, so we're off and running. Here are the terms we arrived at in the case of issues:
* Failed delivery shouldn't be a problem as it'll be via DHL who require a signature
* In case of DOA the buyer will send them back to me (his expense) and he would receive his bitcoins back from Graet once I receive the singles back. Once I've received the singles back from BFL (warranty replacement), the buyer would send the coins back to Graet and he would send them to me once the buyer receives the new working singles.
Just want to apologise to one of the early bidders (you know who you are) who was trying to get funds together in time. I'd really have like to have waited for you as I know you were very keen, but time is of the essence unfortunately
Hope you understand, and I hope you find some singles elsewhere.
