If you’ve been waiting until the last-minute to shop the best Prime Day deals, you’ve just about run out the clock. Today marks the end of Prime Day, which, this year, was four days long. And we can’t blame you if the sheer volume of sale has made your head spin, and the extended time window has you wondering if the deals are changing each day.

The four-day summer sales event officially ends tonight, Friday, July 11. This is the tech giant's 11th Prime Day event during which the online retailer offered up millions of deals over more than 35 categories including electronics and kitchen , apparel and accessories.

Amazon Prime Day sales looked bumpy at first this week, with year-over-year comparisons for the first two days down. But by Friday, early data showed solid sales for the tech giant despite economic uncertainty.
