Airtronics (and subsequently, Hobby People) are out of stock. I talked to Ferrel at Airtronics and he said it would be 2 weeks anyway before they had anymore stock. Fortunately, I think I got the last MT-4 that Amain had on Friday. It said "Limited Quantities" when I got there, then after my order it was out of stock.
So, yeah I'm paying for all my receivers, but I'd rather have the radio in hand and pay a little more than wait for it for who knows how long. BTW, I also had trouble finding anyone that was going to honor this promotion. I called and emailed several dealers and they either had no idea it was going on, or said they were not participating. Amain and Hobby People are probably the safest bet when stock comes back in.
