Amazon offers its Prime members the Jarden Ball 32-oz. Wide Mouth Jar 12-Pack, model no. 52505, for $8.99 with free shipping. (Non-members can spend $49 or more to qualify for free shipping; otherwise, shipping costs an extra $11.15.) That's a buck under our May mention and the lowest total price we've seen. (It's a current low by $4.) They're designed for fresh preserving whole fruits and vegetables like peaches and green beans.
Walmart offers the Ball 8-oz. Quilted Jelly Canning Jar 12-Pack for $7.92. (Amazon offers it for the same for Prime members with orders of $25 or more.) Opt for in-store pickup to avoid the $5.97 shipping charge. That's the lowest price we could find by $2. Each jar comes with a band and lid.
