Walmart offers the Ball Regular Mouth Pint Mason Jar 12-Pack for $7.68. (Target charges a few cents more.) Opt for in-store pickup to avoid the $5.99 shipping fee. That's the best deal we could find by $2. This set includes 12 16-oz. jars with lids and bands.

Update: Target now offers it for $7.49 with in-store pickup.
