Got these today, all four have expiration date of 7/20/22 
I’m sorry about that. These were pulled from Amazon and they’re usually pretty good about discarding expired goods. Please reach out to Woot! Customer Service. To speed things up, let them know if you prefer a return/refund or a replacement (if possible).
From a browser, use the Woot! Customer Service form.
In the Woot! App, choose Account from the bottom navigation and then Support.
Note: Woot! Customer Service replies go to the email address on your Woot! account, not your Amazon login email if used/different.
