Another David Oscarson pen

I had begun to think that my collection of David Oscarson pens would not see any growth for a while whilst I concentrate of building my Faber-Castell collection. So I was really surprised when my eBay automatic alerts notified me this morning that there was a pen going for about 25% less than then usual discount price. I didn't act on it straight away but mulled over it for most of the day. I do believe that the seller made a typo in entering the item, as the price in the text was the normal price, but the official buy it price was much less.

So after about 6 hours of will I or won't I, I did.
