One of the essential features of the Shopster application is to let the users post new offers and discounts and share it with other users.
For example, if an ordinary user comes across a new discount or offers in a particular shop, and decides to share it with other users (or a specific group of users), he can easily do that using this application. The application provides the GUI to input the relevant information (location, expiry date of offer, visibility of the post etc) and with one click the information will be available for other users to view!
A different scenario is when a shop owner decides to post the offers and discounts related to his shop with profit motive. He can use the application similarly and post the information and share it with other users (Here the post will be mostly public).
