One of my wife's responsibilities for the hospital department she works in, was to buy the swag they give away when doing community outreach and presentations, and the order gets placed October/November for the following year. So, in 2019 she placed her order of the usual pens, pads etc., except that year she decided to also get the little bottles of hand sanitizer. She had cases of it, thousands of bottles, in her office, when you couldn't find it in stores.
