I love a good storage deal and the Western Digital 20TB external hard drive fits the bill. It is at its cheapest yet at $265.99 at Amazon, down from $505.99, a staggering saving of 47%, or $240. As for every Prime big deal days offer, this is exclusive to Amazon Prime members. Non Prime members will pay $279.99.

This Tuesday morning, Amazon is slashing the price by a whopping 47% and brings the cost down to just $265.99 from its original $505.99 list price.
