ProFo is a Chrome extension designed to help you stay on top of your promotions and deals. It ensures you never miss a deal again by saving and storing expiration dates for promotions received in your Gmail. With ProFo, you can easily access a list of deals and promotions right from your Chrome browser, making it convenient to track and manage your discounts.

You can save promotions directly from your Gmail inbox by highlighting the expiration date in the email and clicking the green hat ProFo icon on your inbox toolbar thread. Additionally, you have the option to manually add promotions by clicking the "manually add promotion" button on the popup list. ProFo also automatically italicizes soon-to-expire deals and removes expired deals from the list, providing a hassle-free experience in managing your promotions.
