I don't know if this
Seagate Backup Plus 6TB External Desktop Hard Drive USB 3.0 : STEL6000100 $129 - $30.99 (today's 1 day promo code for 2/3/18 - while supplies last and no rain checks: 9336846) + Free S/H = $99 is a great deal or not ($16.5 / TB). However, like I said before, grab it if you had a need for it before the offer expires. Since it offers a free S/H, you can order online and have it shipped to you free.
If anyone can vouch this is a great SATA HDD, I will probably order 1x. So, please response ASAP before the offer expires by today.
