I signed up for text notifications, and I went to the site once I got the message, and added a FL-600R and Olympus 25mm f/1.8 lens to my cart. I looked around and noticed the FL-900R was added. I removed the flash and lens, and added the FL-900R to my cart. I was going back to add the Olympus 25mm f/1.8 lens, and it had already been sold out. When I got back to the accessories page, the FL-600R had also been sold out. Fortunately, I grabbed the FL-900R and purchased it (as I post this, the FL-900R is still listed, so they presumably had more than 1 copy).
Earlier there had been a Pen-F, but that too has been sold. Most of the bodies are now PL9 and E-m10 mark III's (no thanks).
