With a month until Turkey Day arrives, Walmart, Target and grocery chains are already putting Thanksgiving meal food and supplies on sale. Earlier this month, Walmart boasted its “inflation-free” turkey and sides will be less expensive than last year, with turkeys starting at 88 cents a pound and dinner costing less than $7 per person. On Monday, Target trotted out a similar deal, with a $20 Thanksgiving four-person meal special down $5 from last year and turkeys priced at 79 cents a pound — 20% lower than last year. Both retailers are ensuring grocery prices remain a key topic well after next week’s election to drive sales and build or retain a reputation for value. “In this environment, the constant drumbeat is the customer looking for value,” said Edward Jones analyst Brian Yarbrough.
