These are our picks of the best Amazon Prime Day star projector deals as the annual sales event kicks off on July 8.

Unsurprisingly, the very best deals to be found during Prime Day will be on Amazon's own products, with 50% discounts on the likes of Kindles, Echo devices, Fire tablets, and so on. Some of these will even beat the price cuts we tend to see on Black Friday and Cyber Monday.

This is the first time Amazon’s membership deals event runs for four days. The deals could give the digital economy a big boost.
