I didn't see this posted, but if it has been, I apologize for the duplicate. I just purchased two Diamondback Women's Vital 2 Bicycles at Dick's (B&M) for $179.99 each w/coupon plus tax.
Starting today, Dick's is running a sale for 40% off all Diamondback. The Women's Vital 2 is 50% off, though. Also, this past week, I was emailed a 20% off customer appreciation coupon that does stack.
The breakdown is:
Diamondback Women's Vital 2 Bike: 224.98 - 20% customer appreciation coupon = $179.99 + tax.
Shipping is free if you pick up in-store.
This should work on any other Diamondback bike (40% off plus 20% off coupon). Note that the Diamondback sale starts today and the coupon expires today, so 7/23 is the only day for this deal.
Next best price I can find is $349.99
