I stopped by Hobby Lobby today to pick up a few motors. I grabbed some packages of B6-4 off the wall. I thought I should make sure all of the packages were the same so I spread them out. At first I noticed that this single package was priced less than the rest then I noticed that it contained 2 B motors and 1 A motor. I thought I had heard of packages that contained one A, one B and one C but this one was only marked B6 motors. I thought what the heck and went back to get this package too.
