Beef, veal, pork and poultry saw the most significant price hikes.Walmart's CEO noted how the company has launched internal initiatives that help keep costs from being passed to shoppers."We started working on some programs with our meals around holidays in particular, to ensure that we were pricing those meals at the same price we were the year before. And then this year, even for a holiday like Thanksgiving, we're able to bring down the cost of the meal just a bit," Furner explained."What would not help would be some sort of disruption to the supply chain. So hurricanes can do that temporarily," he added. "Having the right supply, having the supply chains flow across the country, those are helpful to ensure that customers and consumers all over the country are getting the things they need. And if we can do that, then I think we can avoid some of the risks that we may have seen had we gotten a situation where we had big shortages."Investors are also expecting Walmart's Q3 earnings in the coming weeks.
