The first year I owned my bar and St Pat's Day came around, I gave out FREE corned beef sandwiches, of course very popular and people said thanks.
The second year I had grown my business and wanted to repeat the sandwiches but I did not keep any record of how many FREE sandwiches I had passed out. So in an effort to start tracking my sales, I decided to charge twenty-five cents and could track that amount on the cash register. The customers went crazy over the GREAT DEAl and how can you possibly stay in business giving sandwiches away for twenty-five cents?
Lesson learned about perceived value.
