Wish I knew, I bought my last new one from Amazon, with the savings I get on gas (Giant Eagle Fuel Perks) the approx $450 RF1200 (red large) plus $50+ tinted shield cost about $470. I could not find a good deal elsewhere online or at any retailer. (I get 10 cents off per $50 spent, sometimes extra bonus on gift cards and always get close to my 30 gallon max, so every $100 is $6 in gas saving.)
The last one before that was a closeout (RF1000 I think when RF1100 were coming out) at Iron Pony and was about $100 off list. Same with the one before that, local dealer was dropping Shoei and dealing on leftovers. Quint Marcaletti bought one (RF1100 I think) in matte black at the Cleveland bike show last year (Jan 2016) that was a great deal, think it was $200.
You might try checking Iron Pony and a few other places, if you're willing to take an unpopular color you may find a great deal.
PS I just checked the Helmet Shop and their RF1200 solids are $485, about $35 more than I paid on Amazon (sold by Extememoto). Quick search on Amazon most prices showing closer to $490-500
Good luck Bill. New knees, new bike, new helmet I guess saving money drinking Keystone Light has paid off
