Funny, I was just moving a box with a Liberty Optics shipping label on it a few minutes ago...
Scott was pretty much selling vortex at the LE/Mil/Vet/first responder price to everyone with the added bonus of no sales tax. I have not found anyone else who is selling at those prices to the general public, but I haven't really gone searching very hard either.
Expert Voice and Euro Optic both give very good prices on vortex and several other brands to LE/Mil/Vet/first responders, with the best extra discount pricing usually being around veterans day, memorial day, July 4th, and black Friday, but sometimes you'll see extra discounts for a few days at random times throughout the year.
My preference is to buy from Euro Optic instead of expert voice because they're much easier to deal with if there's an issue with the order or items, they know the product, and they typically have the items in stock for immediate shipment whereas Expert Voice drop ships from Vortex and other manufacturers and sometimes there are delays.
