Polexpete's shop doesn't exist on ebay anymore. Another poster mentioned (on Sept '20) it is because he's "moving". Any idea when/if he'll be back? The only other silver DWO option seems to be raffles.
Update: sorry for the mistake - his shop, "cityweekender", does indeed still exist, but has no listings. I was referred to the page by Diplomatico (thank you). I have messaged him asking if he'll start selling the DWOs again. I will update this thread if he does.
