Seems like another one of those pricing mistakes or maybe i've overlooked some fine print?
Other sellers have the same thing at more then double the price which Amazon sellers usually charge more then Ebay and yet the cheapest set on Ebay is $70.... Possibly a typo but it says 1 transmitter and 2 receivers which is hard to believe.

I ordered one with overnight shipping since Amazon is handling fufilment it just to be sure.
