Ah, 'tis the season again. The season of Christmas sales!

This year's sale season begins on Black Friday (the Friday after Thanksgiving in the US) and extends to Cyber Monday (the Monday after Thanksgiving in the US), and it's when companies and retailers offer deep discounts to encourage copious amounts of holiday shopping.

So, check your bank accounts and figure out how many pay cheques you have left before Christmas, because we've rounded up a selection of the best tech-related deals that are worth your hard-earned cash. Some are week-long store sales, while others are early online previews, etc.

Good luck out there. And try not to get trampled.

Amazon is starting things with some deals on a few items, beginning on 17 November and running through Black Friday on 24 November. Remember, Amazon's deals are on a rolling basis, so different deals will go live at different times. In addition to these deals, Amazon will offer an exclusive early deal period starting at 8pm EST on 22 November for customers shopping via an Alexa device.
