Not the best price if you take the cashback deals in to consideration for the EVO model (essentially same drive but is 3-bit and the QVO is 4-bit), but it has free shipping.
Major Differences between QVO and EVO
* QVO is 4-bit VNAND MLC and EVO is 3-bit VNAND MLC
* QVO 3 yr limited warranty or 360 TBW limited warranty, EVO 5 yr limited warranty or 600 TBW limited warranty
* Expect 4k read/write lower performance
