Amid this growing threat, Amazon made crucial changes to its annual Prime Day sale, which started on July 8, to attract more customers. First, it extended the sales event to four days; last year it was only two days long. Amazon has also ramped up advertising of the event’s steep discounts.

This Prime Day deal gives you a huge $50 off the Nikon Prostaff P3 10x42 binoculars. Whether you are an aspiring astronomer looking for crisp views of the moon or an avid nature watcher, these binoculars offer excellent value for money, especially at this price.
