The most obvious difference between the Prime Early Access Sale and Black Friday is the date – Black Friday takes place at the end of November (traditionally, the Friday following Thanksgiving) every year. The Prime Early Access Sale will take place more than a month earlier in October. The Early Access Sale also differs from Black Friday in that it’s a Prime-exclusive sale. This means you’ll need to be a Prime Member – or sign up for a Prime trial – to take advantage of the offers, as is also a requirement for Prime Day. Finally, the Early Access Sale will likely be smaller than Black Friday, as it’s a shorter sale and is advertised as a preview for the main event next month.
