Estate Sale Kit

At the last estate sale I cut my hand on a piece of broken glass. Couldn't find a bandaid anywhere. A customer came up with an unopened first aid kit from somewhere in the house and said I should take proper care of my cut. I decided then and there I would put together a kit with all the stuff we need at a sale. Gloves, trash bags, pens, tape etc...  Before as we're setting up, things are all over the place. If we're not paying attention, things we need get sold!
