I just went grocery shopping and accidentally wasn't charged for several items. Should I just go home and consider myself lucky, or return them to the store and explain what happened?

Returning the items to the store and explaining what happened is the right thing to do. Apologize for the mistake, offer to make up the difference in cost, and thank them for their understanding.
