Beginning in October and continuing for the 48 hours, Amazon Prime customers in the U.S. and 17 other countries will be eligible for discounts. Here's what to expect for this fall's Prime Day. Amazon's next Prime Day begins at 12:01 p.m. PT on Oct. 8 and continues for the 48 hours.

Amazon said on Tuesday that it will host its Prime Day-like sales event, "Prime Big Deal Days," on October 8 and 9. Amazon will hold Big Deal Days in Japan later in October. It has also prepared a holiday gift guide.

Amazon is back at it again with another fall Prime Day sale. The retail giant had confirmed back in September that Prime Big Deal Days would return in October, and now we officially have the dates. The upcoming Amazon sale is set to kick off on October 8 and end on October 9. Similar to Prime Day in July, the sale will only run for 48 hours.
