I do like how they run the trains through all of the theme areas of their display, not just the town. Similar to us at Greenberg last November running the monorail through both the space area and the Winter Village area. It gives a visual sense of cohesion to different theme areas.
Back to Greg’s Paypal box issue, don’t the Bricklink Terms and Conditions state that shipping is at the Buyer’s risk and the Buyer should purchase insurance? I know that many individual stores have that in their stated Terms & Conditions. Probably a good idea to reiterate that especially for sets in boxes (which could be purchased as much for the box as for the set itself). I agree that the whole situation seems a bit fishy and perhaps a money grab.
