Western Digital WD SN740 2TB M.2 2230 for Handhelds US$108.59 / ~A$168.05 Delivered @ Storage Choice AliExpress

For me it came up as $180.60 but seemed to automatically discount down to $160.60 with a 20$ coupon
It also stacks with coins so for me it was $153.23 (including tax) which I thought was a bargain
