Have you heard of these GSBI’s? Apparently a person advertises in the paper or on a bulletin board, Garage Sale By Invitation, and gives a phone number. When people call they are assessed on what they are looking for or how they sound or whatever and then issued an invitation (or not!) to come and view the objects, either individually or at a set time along with others. The reaction to this seems varied, as one might expect, from yet another intriguing foray into human interaction.
