I'm I can usually get out at least 5 - 10 tracts easily on one trip to a store. Last night at a neighborhood Walmart, I gave out several May The Lord Be With You tracts. Wayne took one on the bread isle. He said that he was new to the area and looking for a church. Quadre, an employee, took one in the parking lot. I gave a Yolo tract to Jennifer, the cashier. A man who I saw in the store took one when I was returning my cart. I also left one at the Redbox.
Most people will take a tract. If someone doesn't take one, keep on going to the next one. I have a rule: for every reject, there are 50 more around the corner who will take one!
