It took me a while to figure out that I could back order the FMA XY sensor when it was listed as being out of stock instead of waiting until a new production run came in to FMA.
FMA appears to only make enough to fill back orders as the June 1st shipment that I had been waiting for was immediately gone and the XY sensor status had gone back to out of stock with the next delivery being June 26th.
So I decided to place an order for the XY sensor to see if FMA would accept an order for an out of stock item. Well their system did and I figured that I would get a message stating that the item is on back order and I will get my sensor when the new production arrives on June 26th.
However, I got a message from FMA today stating that the XY sensor is in stock, even though the website page says it is out of stock and is on back order, and will be shipped in a couple of business days. So either I really am going to get an XY sensor or the message is incorrect and I will be getting the XY sensor after the new production shows up on June 26th.
Very strange way of doing business. Advertising one thing and saying another.
