Every year, on the second Sunday of May, Americans show their appreciation for the real-life heroes in their lives — moms — with special treats and lavish gifts. This Mother's Day will be no exception. A National Retail Federation (NRF) survey of 7,818 people revealed that the approximately 83 percent of US adults who plan to celebrate the holiday on May 9, 2021, will each spend an average of $220.48. The total, an astounding $28.1 billion, is the highest amount in the survey's 18-year history and easily topples 2020's record spend of $26.7 billion.
