The only things that I can think of that are normally around that price are the two commanders, the Siege Skywarp set (which would be sold out anyway), and the two ER seeker sets. And I'm pretty sure he has those all, anyway.
Interesting, having just been to amazon.com a message popped up saying the site will only show me items that ship to the UK and to change that I need to change my address. Never had that before. So the geoblocking they do is based on the physical address in your account as opposed to your IP address?
