Michigan woman hits Reddit gift exchange jackpot with Bill Gates as Secret Santa

According to WDIV-TV, users who participate in the social media platform's exchange post information about themselves to provide potential Secret Santa personalized gift ideas, and Shelby has, herself, been a Secret Santa to 95 strangers over the years.

She knew something odd was afoot, however, when she received a notification just before Christmas.

"I logged into my tracking page, and I saw the package weighed 81 pounds," Shelby told the news station, adding, "I thought that was really unusual for somebody to overnight an 81-pound package to me. I figured that was probably extremely expensive."

So what exactly did Shelby receive from her billionaire Secret Santa?

According to the Detroit Free Press, Shelby's massive haul included:

• Bill’s Deck of Books 2019

• A Harry Potter Santa hat

• The Legend of Zelda Hylian Shield earrings

• Handmade Zelda quilt

• A hammock with bug net

• Almond Roca

• Mint chocolates and other candy

• Toys for her cat

• Seven packs of assorted Oreos

• A cat-themed logic game

• Eight hardcover books

• A manuscript copy of "The Great Gatsby"

• A candle inscribed with a passage from "The Great Gatsby"

• Two adult-level LEGO sets: Harry Potter Microscale Hogwarts and the retired Star Wars UCS R2D2

• Twin Peaks gifts, including an embroidered L.L. Bean jacket worn by crew members during the second season of the show.
