It is somewhat amusing, with most things, when they are discontinued, (generlly because they are no longer selling well), and dealers discount them in order to get rid of them, with firearms, it seems that when a model/caliber goes out of production (again, because its not selling well - enough-) many people immediately RAISE the price of existing stock, because NOW, they are "collector's items".
7mm-08 Savage 99s were made in (apparently) small numbers in the last couple years before Savage ended the model 99 production.
Small number made, fixed supply (out of production) so its a case of paying whatever the guy who has one wants for it.
I recall one time, just after Winchester announced closing their last US plant, everything marked Winchester at the gun show jumped in price. Long guns went up about $100 and all the other Winchester stuff, from pocket knives to tie tacs went up 20-50%.
came down a bit after a while, but never went back to what it was...
then went up again, later...
