Looks like UMART has dropped about $100 across their range of NVIDIA 1070 graphics cards. Cheaper than any listing on staticice
Similar price reduction on 1080 range too. Stock in some models, such as the Gigabyte in the link, and others on back-order.
I'd avoid Umart. Their customer service and warranty is on par with old school msy. Trying to weasel out of replacing a faulty item (within the "7day refund for a fault" policy advertised) then trying to charge a device fee because the faulty case require them to look at the case with all your working parts in it. Kind of a joke if you ask me.
I'd go somewhere else
