The Fort Pierce Walmart posted to its Facebook page Friday that the Khalil Mack Foundation had paid off all active holiday layaway accounts at the store.
A Walmart spokesperson told Jeremy Mikula of the Chicago Tribune on Monday that Mack paid for "300 to 350 accounts—about $80,000 total."
"His foundation came to us and said he wanted to be a secret Santa," store manager Mathias Libardi told Lamaur Stancil of TCPalm.com in a story published Saturday.
Mack's generosity isn't limited to the holiday season, as he donated cleats to Fort Pierce Westwood High in June. "We knew Khalil [Mack] was going to contribute to the school, since he always gives back to his community, but we didn't expect this," head coach Jeff George told Elliot Brownstein of TCPalm.com at the time.
On the field this year, the three-time All-Pro has registered 7.5 sacks, 13 quarterback hits and 41 total tackles across 13 starts for the 7-6 Bears.
