The family-friendly offer is back! For a limited time, McDonald’s is offering Chicken McNugget lovers a great deal — a 20-piece order for just $5 at participating locations. It’s savings worth noting because a 10-piece order is regularly priced at $4.79, so, for just 21ยข more, you double your order. You’d be silly not to order the 20-piece. It’s enough nuggets for friends and family to dip with you.
