I know this will apply to only a small percentage of you, but it's so great!
The Giant store in the Park & Shop Center near Mary Washington College in Fredericksburg, VA is now giving a 5% discount to MWC students and employees. It isn't supposed to apply to alumni (which I am), but I went and talked to the manager, and he agreed to give me the discount, too. I'm sure he'd agree if anyone else asked as well. They will give you a new Bonus Card that includes the discount, and it comes off your total at the end.
Every little bit helps! I hope someone reading this can use it!
