Walmart saving Millions

Walmart saves 27 million by making two adjustments. Walmart CFO Brett Biggs explains how the chain is paying attention to cost savings in its 2017 Investment Community Meeting. Their first change was described by Biggs as a "small" change to the plastic bags used by Walmart US. That change saved them 20 million year over year. The second change the company made was shortening the length of receipts given to the customers in stores. This saved the company 7 million over the last year.
