Just three months (technically less than) after the 10th Prime Day in July, Amazon is already back in "Prime" mode. This time, it's for Amazon's third annual fall sale: officially

Amazon Prime Big Deal Days, also known as October Prime Day because of the exclusive deals, will start on Tuesday, Oct. 8, and end on Wednesday, Oct. 9. Though the specifics of what is on sale are not fully known, the tech company said shoppers could kickstart their holiday shopping, prepare for the winter and score on Halloween items.

Amazon's mega "Prime Big Deal Days" kicks off October 8 and we expect some big discounts before the holidays — but we also predict some hot ticket items will sell out. Here's what we think will go faster than ever this year.
