My lesson that was learned, was never to have my dealer order something that wasn't in stock. The first time, I think he was trying to get a group rate, or ordered from the lowest priced distributor to get a few more bucks in his pocket, without having one in stock at that end. This was back when Form 4's were 4 months out, and it was 9 months of waiting to get my can.
Second time, I had my new dealer order one for me. Apparently all three of their normal distributors were out of stock, and it took two months to get a serial for my Form 4.
Of my other two cans, one was in stock at another dealer, and the other was one I ordered from an out of state dealer with one in hand, shipped to my dealer. This is how the purchase is going with the one I ordered today too.
If the dealer doesn't have it, I'm moving on.
