You must use Amazon's Price Check app on Android or iOS, which gives users the chance to scan a bar code, take a pic of the item, or use a traditional text search to find the item, price, details and reviews of products.
When you walk in stores, Amazon is asking that users submit prices of items via the app, so that the company can confirm they have the lowest prices. The promotion is good for 5 percent off, up to $5, for up to three items.
Snowe says:
Amazon's promotion -- paying consumers to visit small businesses and leave empty-handed -- is an attack on Main Street businesses that employ workers in our communities. Small businesses are fighting everyday to compete with giant retailers, such as Amazon, and incentivizing consumers to spy on local shops is a bridge too far.
Amazon says the app is just that, a price comparison method, and that the app gives comparisons to brick-and-mortar and e-tailers that aren't Amazon.
