Walmart offers the set of two Cap Barbell Rubber-Coated Hex Dumbbells with prices starting from $10. Opt for in-store pickup to dodge the $4.97 shipping fee. That's at least $14 off and and tied with our expired mention from yesterday as the lowest price we could find. They feature non-slip handles, with weights starting from 5 lbs. and going up to 50 lbs.
