As of 4/19/17 recheck, most of these offers expired… You can find the “survivors” in the “Elsewhere at Amazon” sections of the almost-daily Lightning Deal round-ups…
Groupon has launched a new two-day sale until Tuesday night, and among the Electronics items offered are a handful of Western Digital Elements USB 3.0 External Hard Drives with free shipping and free returns and a 6-month warranty from Western Digital. The 750GB model goes for $40, the 1TB for $45, the 2TB for $70 and the 3TB for $95. This ships faster than the typical Groupon sale (“ships in 2 days” it says). No PO Boxes.
Speaking of storage, in addition to the Sandisk potpouri mentioned earlier today there are a couple more at Amazon (grouping them together saves from additional posts):
+ certified refurbished 500GB Seagate Wireless Mobile Portable Hard Drive for $30, sold by 3rd-party, fulfilled by Amazon (Prime eligible); limit one per customer
+ new condition Drobo 5D: Direct Attached Storage Base Unit (5 bay array – USB 3 and Thunderbolt ports, model DRDR5A21, HDDs NOT included) for $500
