Detecting Costly Refrigerant Leaks
An average food retail store leaks an estimated 25% estimated of its refrigerant supply per year. The majority of refrigerant leaks, which are caused by a number of factors, occur in racks and cases. For an individual store, this loss can add up to a sizeable annual expense; for a regional or national chain, the costs can be even more substantial. Additionally, associated labor costs and the potential loss of business because of service disruptions when fixing a leak should be factored in. -
Walmart challenging Amazon with shipping offer
The world's largest retailer is throwing a counterpunch to Amazon's Prime service. Walmart is offering a free 30-day trial of its ShippingPass program, which offers consumers unlimited, two-day free shipping for a year. Normally, the service costs $49 per year. (So as not to feel left out, existing ShippingPass members will receive a free month of the service).
