In Norway are not blessed with many gamestores that actually carry BT stuff. Since we are not in the customs union ordering from other countries can often increase the price by quite a lot since we have to pay VAT on shipping and charge for custom clearance.

See that one local store have the Tactical Operation Books (Advanced Rules and Advanced units and equipment) but the image on the store are the fourth (Rules) and first printing (units). I am going there this sunday to see for myself, but are first printings still usable. See that the current ones are sixt printing for both.
