Do you sell gift cards? Do they expire? Do they have a service charge when not used for awhile? Are they too at all DG locations? Are they available for $50 ? Thanks

Yes

Yes, no, no, yes, yes

They do stock many different cards. They can't expire any longer and any fees are unlawful. They're treated the same as cash. The amount on the gift card will be up to you, depending on the card you choose...
