Walmart offers the Fuel Pureformance 20-lb. Soft Kettlebell for $25.04. (Amazon charges the same with free shipping for Prime members.) Opt for in-store pickup to dodge to the $4.97 shipping charge. That's the lowest total price we could find by $30. It features an iron sand filling.

Of note, your purchase at Walmart also includes a 30-day trial of Daily Burn streaming workouts.
