No doubt you may be eagerly anticipating the arrival of more than a few Black Friday/Cyber Monday purchases to be delivered. If things go south, that means dealing with customer service… well, now there’s an app for that. If your package doesn’t arrive on time, skip the customer service number and download the Paribus app instead. The app scans your email account for package delivery information, tracks your package and automatically files a claim for a refund for you. Not only that, Paribus will even scan prices and file a claim for you in the event of a price drop.
