Compare Textbook Prices with Bookholders vs Tech Bookstore App

DESCRIPTION

The Bookholders vs Tech Bookstore App by Michael Beck is designed to help students compare textbook prices efficiently. Users can search for textbooks by ISBN, title, or author, allowing easy access to price information from both the Bookholders and Tech Bookstore. The app operates by sending concurrent HTTP requests to gather prices, but it has some design issues that require manual page navigation and might lead to extra requests if multiple results are found. Improvements such as a threaded approach could enhance performance and user experience.
