Every February 14, people worldwide demonstrate their affection for family members, friends, teachers, and significant others with a gift or two. However, this display of love does not come cheap. The National Retail Federation say that 55% of Americans will celebrate Valentine’s Day this year, spending an average of $136.57 USD each. Though lower than the $146.84 USD expended in 2016, it will add a respectable $18 billion USD to the economy! It is no wonder that retailers love the holiday.
