Now that April showered it is time for May to bring the flowers and good produce at the grocery store for those of us that are not fortunate enough to have a green thumb at gardening. All of May all you have to do is have a Discover Card and sign up for their promotion to get 5% back on Groceries up to $15. The bigger savings is with the restaurants up to $1,500 for the quarter if you are signed up on the same cards. If you are a Chase cardholder of the Freedom card you can get 5% back on groceries up to $1,500 for the months of May and June. If you are not getting any cash back on your grocery purchases you have the wrong card!
