Amazon's Prime Big Deal Days event runs from Tuesday, October 8, through Wednesday, October 9, but we're already seeing sales on smartphones and accessories. These are our favorite Prime Day phone deals so far.

An Amazon Prime membership is $14.99 per month or $139 per year if you choose to pay annually (the monthly rate for that is about $11.50). But right now, Amazon is offering a special Prime deal: You can get three months of Prime for just $7.49.

Amazon Prime is one of those reasons, if not for the faster delivery that you get alone. However, Prime comes with a lot of additional perks, one of which is Prime Day, giving Prime subscribers access to tons of exclusive deals. We had a Prime Day in July already, but Amazon is lining another one up for next month.
