I've watched prices go up steadily since 1963, sad to say. I remember when primers were .29 cents a hundred, and everybody sold them, including the local drug store. Surplus IMR 4831 was .35 cents a pound, and it came in paper bags with the wire roll top.
It's not going to get any better, either. Fewer and fewer retailers are carrying reloading supplies, so the local guy can pretty much set his own price, according to his/her overhead and conscience.........
Hope this helps.
