If you ordered an Antarctic expedition prop set on Saturday you paid too much for shipping.
Not surprisingly, it's my fault this happened- I had set up the charges as though each package included three notebooks, which are surprisingly heavy, instead of the lighter shipping weight of one notebook, a patch, and a pin. To make up for the problem, which was totally on my end and resulted in an overcharge of $1-$1.50, I'll include an extra Miskatonic University notebook in every order made before 2100 PDT on Saturday (when I finally determined what was going on and fixed it).
I sincerely apologize for the error and hope everyone caught by it finds the extra notebook an acceptable way of making up for it. As a small operation serving a very niche market I take customer service very seriously, so I'll be happy to refund the overcharge amount to anyone that prefers that form of compensation. Please don't hesitate to contact me if you ever have a issue with an order.
