Not many things would sell that way.  People burning the time and gas to go to a brick-and-mortar store have expectations.  For lots of stuff it means being able to see, touch, or try the actual product they want to buy.  Otherwise they'd just shop online.

Might be cheaper to mount a bunch of those popular tin signs that say, "Anyone Found Here at Night Will be Found Here in the Morning" or, "We Don't Call 911" or, "Warning: There is Nothing Here Worth Dying For."  And there are the ever popular "Monitored by Smith & Wesson" and "Beware of Dog:  He Eats Everyone His Owner Shoots."  Or, if you're not on good terms with your neighbors or competitors, there are huge signs one can pound into the ground that say, "My Neighbor Wants to Ban all Guns!  Their House (or store) is Not Armed! > (with arrow or a hand pointing to neighbor's house or store).

But seriously, hardly anyone would want to relive the retail experience as might have been back in 1890.
