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

Online spending is expected to surge to $23.8 billion across U.S. retailers during a 96-hour Amazon Prime Day event this week, according to an Adobe Analytics forecast released on Monday, as shoppers seek strong discounts on back-to-school gear ranging from apparel to electronics.

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.
