Don't know if this has been posted yet.  Has anybody heard of this offer where you get $50 back a month for spending $100 on groceries and $100 on gas at the same stores?  The link is below that explains the details. A friend emailed this to me wondering if it is legitimate and I haven't heard of it.  Has any savvyshopper out there done this and what was the out come?
