This preorder offer on the new Nothing Phone 3 is my favorite Prime Day mobile deal

Amazon Prime Day runs from July 8-11, but one of the best mobile offers I've seen is open to all. That's right -- you don't need to be a Prime member to snag these savings, and this smartphone is already under $1,000. 

The new Nothing Phone 3 just launched this month, and Amazon already has a tempting preorder offer.

If you preorder the Nothing Phone 3 on Amazon, you can scoop up the 512GB model for $799. That's a $100 discount on the 16 + 512GB model, and a chance to swipe up double the storage for the same price as the 12+ 256GB model, which is also available for preorder for $799. You save $100, get twice the storage, and get the new Nothing Phone 3 when it ships on July 15.
