But there's one gift he won't buy you, no matter what the price is.
A 24-year-old Reddit user by the name of Rachel decided to participate in the website's online gift exchange this year, which paired her with another user by the name of Bill.
Imagine her surprise when she found out Bill was the Microsoft co-founder himself.
The multi-billionaire made a donation in her honor to Heifer International, an organization that aims to end poverty. He also sent her a stuffed cow and a "National Geographic" travel book.
Rachel posted a thank you to her Secret Santa after receiving a gift she says was "perfectly and EXACTLY tuned into my interests," but added, "sorry for the apple iPad on my wish list, that was really awkward."
