Walmart discounts the Cap Barbell Vinyl-Coated Dumbbell in a variety of weight options, with prices starting from 85 cents. (Prices are as marked.) Opt for in-store pickup to avoid the $5.99 shipping charge. That's tied with last week's mention and at least $2 under the best price we could find for a similar dumbbell. They're available in weights from 1 to 15 lbs.
