A young woman stops into her local pharmacy to pick a supply of tampons 
for herself. She goes to the aisle where they are located and sees they 
are priced at five boxes for one dollar. Thinking this is a misprint; she 
finds a clerk and asks if this can possibly be the correct price. 

The clerk replies, "Yes it is the correct price. For one week only, you 
can purchase five boxes of tampons for one dollar, no strings attached."
