Walmart offers the Ball Wide-Mouth Pint Mason Jars 12-Pack, model no. 66000, for $8.47. Opt for in-store pickup to avoid the $4.97 shipping fee. (Amazon charges the same price with free shipping via Prime.) That's 71 cents per jar, tied with our mention from two weeks ago, and the lowest price we could find by $5. They come with bands and sealing lids.
