It is real easy to figure that a large store may be gouging when you see a smaller "mom& pop" location selling for a much lower price. However the high volume dealer sees the need to raise his prices sooner when he reorders at the new pricing reality. Recall that the Canadian dollar was at 1.10 US a short time ago --now it is at .90 US. After the banks get their cut this is a 25% differance in cost. Then if the ammo manufacturer has put up prices 5%, thirty percent higher is just the new reality.
If he does not keep on top of inventory adjusted replacement value a small shop will find that it is selling at its new stock replacement cost. The whiners will be his best pal for a while and then crap all over him on a site like this when he does adjuct his prices on new inventory.
