As one of its daily deals, Amazon
cuts up to 74% off
a selection of Sony memory cards, external hard drives, and portable USB chargers
. (Prices are as marked.) Plus, Prime members get free shipping
with no minimum purchase required. (Non-members can spend $25 or more for free shipping; otherwise shipping starts at around $5.) That's the first such sale we've seen on Sony memory products from Amazon and yields several price lows. (For further comparison, we saw up to 80% off selected Patriot memory items three days ago, since expired.) Sales tax is added where applicable. Deal ends today.
A best bet is the Sony 1TB Gauntlet USB 3.0 Portable External Hard Drive (pictured), model no. HDE1/B, for $89.99 with free shipping ($0.09/GB). That's the lowest total price we could find by $17. It features a maximum data transfer rate of 5Gb/s.
