Update: This sale has ended, but some of the kettlebells are still heavily discounted.

Walmart currently has Cap Barbell's Cast Iron Kettlebells on sale in a variety of different weights, some of which are discounted by almost 50% off.

Cap Barbell's Cast Iron Kettlebells help engage multiple muscle groups at once. With the cast-iron construction, there's a durability to these products which can't be overstated. Even daily use will have little effect on its surface over time. Follow exercise techniques and just one kettlebell is all you need for a total body workout.

This sale is available for the following weights:

You'll also receive a free 30-day trial of the workout video streaming service Daily Burn with your purchase.

If you've still got more gas left in the tank, Walmart also has Cap Barbell's Hex Dumbbells (set of two) on sale currently as well. Pick up a 10lb set for only $9. The 20lb, 30lb and 40lb sets available on that page are heavily discounted right now too.
