To avoid copyright violations, Amazon does not return the computer-readable text of the book. Instead, it returns a picture of the matching page, instructs the web browser to disable printing and puts limits on the number of pages in a book a single user can access. Additionally, customers can purchase online access to some of the same books via the "Amazon Upgrade" program.
A price comparison app or website allows you to compare prices for products. The app shows you the product prices from different retailers to show you where to buy the product affordably. Some apps require you to scan the barcode while others allow you to type in the product name to find your product. The price comparison website then shows the customer a list of retailers who are selling the same product, and how much they’re selling for. Those looking to save money on purchases are more likely to use a price comparison app. To attract budget-conscious customers you’ll need to offer a lower product price. However, it isn’t necessary to lower your product price to attract customers to your store.
