Less than one week from Christmas, local supermarkets are dealing with more store traffic and significant demand for cooking ingredients.  With more people expected to eat at home and travel less this holiday season, Tadych’s Econofoods Store Manager Jon Calhoun says the spikes in grocery store transactions have strained the food supply chain. Still, Tadych’s has been able to keep up to this point.  He says the baking goods have been even more popular this year. [CALHOUN]  Calhoun advises shoppers to pick up their holiday turkeys and hams soon because supplies could very well be tapped out by next week.  According to estimates from the U.S. Census Bureau, sales at grocery stores increased nearly two percent in November despite overall retail sales declining last month.   Grocery store sales in 2020 have shown an increase of over 10 percent from last year through November.  Overall, the National Retail Federation has projected holiday sales this year to grow between 3.6 percent and 5.2 percent compared to 2019.
