Walmart offers the 3M Bondo Home Solutions 1-Quart All-Purpose Putty for $9.23. (Amazon charges the same with free shipping for Prime members.) Opt for in-store pickup to avoid the $5.99 shipping fee. That's tied with our mention from three weeks ago and the lowest price we could find by $8. It includes 1.9 lbs. of putty and 1 oz. of hardener.
