Around here the Shoprite has you spend $300 in about a 5 week period and you get a choice of certain things..
Here's a link for you.. (there are too many things to show)

However, Wegmans has no promotions, Genaurdi's and Acme no promotions, Bottom Dollar/Aldi's no promotions so really it is only one store that has the free promotions. To my knowledge, Pathmark has no promotions.
I think Giant has a promotion but they are in PA, and I'm thinking of the Southern NJ stores.
For me, I wound up getting a Shoprite 17 pound turkey (regularly $23.00) for free.
