The countdown is on for Amazon’s Prime Big Deal Days, which officially kick off tomorrow (7 October). But you don't need to wait until the main event shop the best deals – early offers are dropping thick and fast,

Amazon now has two Prime Day shopping events per year. Oct. 7 and 8 is Prime Big Deal Days, and we're answering common questions before the big event.

We’re talking about tech upgrades like this SanDisk 2TB Extreme Portable SSD, which would normally cost you $210, but is currently on sale for $150. There’s no way this deal lasts for very long though, so if you want to get this device, you’ll want to do so soon to avoid missing out on the discount.

Grab this BLUEAIR Blue Pure 511i Max air purifier on sale right now during Amazon Prime Day. The $140 appliance is now under $95.
