Everyone uses them. No store, not even Costco or Sam's, makes a box big enough for me. They'd become collectors' items. I asked around to see what types of things my friends would prefer to T-shirts and candy. One asked if we could sell food.
Some schools do.
Oh, how fondly I remember Market Day, when we had to pick up pounds of frozen steaks and pre-packaged lasagna. We would buy all this food and wind up giving it away. The students could tell their stories, talk about their teachers and their dreams and their ambitions. They could sing, if they sing, and do skits if they are dramatically inclined. They could read excerpts from Shakespeare or from their own works, which are more compelling for those who like only contemporary literature.
