I'm not sure how much you remember about the project, but you designed a book buying app that used a barcode scanner and a database file to show prices for books.
I need a few changes made to the app. I am not on a deadline this time, so it is okay if you don't have much time to spare right now.
If you need the source code for the app I can give it to you. The changes that I need to the app are:
1. On the "home" screen, display an expiration date that is stored in the database
2. Instead of showing just one price, show 3 different prices (one for each "type", all of which are in the database) and allow the user to choose one
3. On the "view cart" page, display the "type" of the book
