Gift Cards

Our local grocery store has the amenities to offer gift cards for other purchases.  We bought a gift card which can give a discount on car gas, today.  We only received 3 cents off per gallon, but since the gas prices are going down, it help a bit.  I often get cards to give for special occasions, and it would be nice if my family members would keep them and then I could just fill them back up, when needed.  Either way, I guess it doesn't matter, except for waiting for the online store to ship it.
