There's another big Amazon sales event coming on October 8 and 9. Here's how to get a head start on finding the best prices on the tech you want before the holidays.

Amazon Prime Big Deal Days are mega-event sales during which Amazon slashes prices on tens of thousands of popular items. The sale lasts for just two days. Inventory on many products that go on sale is limited, so if you want to get the best deals, shop early to snag the items you want at a deep discount.

Go to the main Amazon Prime page and click on "Try Prime," then follow the instructions. Note that you need an Amazon account before you can sign up for Prime, but if you don't yet have one, it's easy to set up. Go to Amazon and enter your details to create an account, then add Prime to get the 30-day free trial.
