Walmart continues to offer the Tone Fitness 5-lb. Vinyl Kettlebell for $3.99. Opt for in-store pickup to dodge the $5.99 shipping charge. That's tied with our mention from two weeks ago and the lowest price we could find now by $13. It's filled with cement and features a 1-piece vinyl coating.

Note: Amazon offers it for the same price with orders of $25 or more.
