They also used to sell a "7 for the price of 6" deal, but now they just have a Pro-pack. I'm not sure if that's just 6 or 7.
For my comment:
Dunham's, not Dick's. I knew Dick's didn't sound quite right. I opened a box and found a couple 3701s in the bag from the store...Dunham's. They're not as common as Dick's, but every time I go into one, I find 2-3 3701s actually on the shelf.
Interesting. Do you have a picture of your entire system?
I just finished the vehicles (no planes yet). Included here are all the official ASL vehicles plus vehicles from Bounding Fire Productions, Heat of Battle, Le Franc Tireur, and I believe a few from Kinetic Energy.
