Walmart offers the Bowflex SelectTech 552 Adjustable Dumbbells for $199.35. Order via in-store pickup to drop the price to $189.18. Outside of the deal below, that's the lowest price we could find by $70. (We did see them for $7 less two weeks ago.) It features 15 settings on each dumbbell with an adjustable dial system for weights of 5 to 52.5 lbs.
