JulieFlyGal, can't remember where you're from (Syd I think) but try Oakley directly if there if they have an office/showroom close by. Here in Melbourne they provide generous discounts for pilots, 40% off the top of my head which definatly makes it cheaper than buying from the states.
The DFO at Moorabbin Airport also passes this discount on to pilots.
Oakley is the Australian distributor for Serengetti if that happens to be your preference.
