I received a personalized coupon with my latest order from OpticsPlanet. It expires in 30 days, and I'm not going to use it. Probably only good once, so PM me if you're going to buy something from them this Christmas. Order has to be over $200 to use the $20 coupon.
I got something else in the mail from Optics Planet yesterday, and the box came with two more coupons that I think can be used more than once, so I'll post them here.
For $30 off $250, use promo code 30NOW (expires 12/31/13)
For $20 off $250, use promo code 20LATER (valid from 1/1/2014-1/31/2014)
I still have the code from my original post, but I'll wait 'til someone PMs for it, because I think it can only be used one time.
You might be better off "requesting a deal" on an item. The best way to go is to find what you want in stock at a competitor and get them to do a price match. OpticsPlanet is awesome like that… I found an EOTech XPS2-0 for $445 at CMC Gov Supply. I asked OpticsPlanet to price match, which they did, and it saved me the money on TX sales tax.
