Garmin "Bucks" or Avidyne discounts at Oshkosh?

Does anyone know if Garmin will be giving our Garmin “Bucks” for avionics upgrades? (Looking specifically for upgrading to a GTX345 transponder).

Same question for Avidyne products - any rebates or discount coupons at Oshkosh for avionics upgrades? (specifically for the DFC-90 autopilot).



Following this closely; I’m getting my 345 install early in August. Any $$$$ I can save, the better!
