I have no secrets of any value except that the shows I go to are sparse for interesting, classic rifles. So, I tend to watch the isle walkers. The cool gun may be on someone's shoulder. In fact, I'll watch the entrance line and even the parking lot. I once bought a highwall that never made it out of the parking lot (with cash - good point Michael), and could have sold it three more times before I got in the front entrance.

I never hesitate to ask a dealer or walker if they would be willing to sell a scope or sight that I like w/o the rifle. If they say no, I don't argue, but I've gotten good deals that way on hard to find items.
