Every WM, that I have been in (10 or so in OR and WA), has a glass case, built into the counter top, in the sporting goods department. It makes up a small fraction of the total counter space where the guns, ammo, knives, fishing reels are displayed and kept. Clerks typically stand behind it. Inside this small glass display you will find the close-outs, unboxed and discontinued items. It can be cluttered inside this case so ask to see everything.
Typically, this part, on top of the glass, of the countertop has papers and boxes and junk covering the stuff below so you must clear off the glass top and then hunt and peck. This is where you might find the SOG Powerlocks if they have any. I prefer to check for myself, in person, but sometimes I call ahead.
Have you run into any Buck Mayo Hilo knives? How much are they going for?
Happy hunting.
All the best,
