I'm sorry you didn't receive what you should have, but overall I was very impressed with their QC. I received the game at the same time as the expansions and it took me well over an hour of sorting and checking to verify that everything was there. g/l on getting your RPG supplement.
I received my second shipment all in one padded mailer. Inside were two white boxes. The RPG came in a box a little thinner than the box the expansions were in but the same height and width. The add-ons I received at the time were loose in the mailer.
