These normally sell for $299, but for a limited time, Amazon has the Bowflex SelectTech 552 Adjustable Dumbbells for $200.33, shipped free with Prime. That's after clipping an on-page coupon good for a $98.67 discount.

If stock runs out or that coupon doesn't appear for some reason, try Walmart: They also have the SelectTech 552 for $200.33 when you add it to your cart and choose in-store pickup.
