Have you count the way buying regular AR individually? It probably work in that way.
I wouldn't call it a scam since you still get what you paid; you just didn't get any discount. And they didn't really pricing the limited AR transmitter. It could be either 200SC or 2000SC or even 7000SC, and I'm pretty sure some ppl will still buying with that price.
On the other hand it is an obsolete marketing/advertising way that make you feel annoying. It would be nicer if they simply say 'buying a limited AR package coming with 2 limited AR!' in my opinion. But people will still criticize anyway because they named GF and have a pretty GF style shop with old fashion GF interface...you can't change people's impression by a day or two.
