KEY POINTS
  • Prices for foods popular among football fans, like avocados and chicken wings, tend to rise ahead of the game.
  • American adults say they'll spend an average of $81.30 on the Super Bowl this Sunday, according to a survey from the NRF.
  • The price of chicken wings increases about 7 percent for about a week before the Super Bowl and then falls 4 to 5 percent for a week after the game.

As Super Bowl celebrations become increasingly focused on food over the last 10 years, prices for game day favorites rise and fall with fans' demand.

In an annual survey, the National Retail Federation found a 15 percent increase over about a decade in the number of people planning to buy food and beverages for their game day celebrations, said Katherine Cullen, director of industry and consumer insights at the industry trade group.
