I'm about to buy the Captain Sim 757 for Flight Simulator X. But on some online stores, each Captain Sim 757 has a different price. The JustFlight Captainsim 757 is $34.95, the CaptainSim 757 is $40.50. Why are they both different prices?
What is the difference between the JustFlight CaptainSim 757 & the CaptainSim 757? PLEASE I NEED ANSWERS SO I AM NOT RIPPED OFF!
