Tonight marks the conclusion of Prime Day, and Amazon is making a concerted effort to slash prices across a wide array of products. With the countdown underway, shoppers are encouraged to seize these fantastic deals before they vanish at midnight.

When buying the Galaxy S24 Ultra, the most recent Galaxy phone Amazon will accept for trade-in is the Galaxy S21 Ultra, which it priced at $135. Samsung values the exact same handset at $600. A mind-bogglingly large gap in valuation between the two companies.

Prime Big Deal Days officially ends after today, October 9. Like Amazon Prime Day this past July, this sale will see deals drop across the retailer’s site—but the savings are only available to Prime members. If you want to get in on these deals (and enjoy free, speedy shipping), you can sign up for a free 30-day trial at any time.
