Pros:

• Genius idea to crowdsource easy labor tasks
• Anyone with a phone can do this
• Retail execution has a lot of mundane tasks that can be easily verified with screenshots ... which is perfect for smartphone users looking for paid work
• Big box retailers can reduce employee costs if they can simply pay contractors for "contract" tasks

Cons:

• People who work for some of these companies (big box retailers, brick and mortar retailers) will lose their jobs as they have fewer responsibilities
