Via VFTW, there’s a promo code which is currently working to get $10 off an Uber ride to be used anytime before May 1, 2018. This won’t last.

Promo code: localfavorite

Worked for me at 5:07 pm ET.

Update: worked for me and for some, but others are getting “already used this product” error message. Might depend on home state or some other factor.
