Starting Halloween weekend and going forward, Lyft is extending the program to include Thursdays and they're upping the number of coupon codes available from 5,000 to 6,000. Additionally, for Halloween weekend, the codes can be used on Monday night for anyone who refuses to reveal their Ken Bone Thugs 'N Harmony costume until it's actually Halloween. (That's a freebie, you can use it.)
Previously available in New York state, Colorado, Illinois, and Florida, the deal has now officially been extended to Washington D.C. as well.
On a standard weekend, codes can be used anytime between 10pm and 1am, Thursday through Sunday. But the codes get gobbled up fast. You have to enter the code into your app as soon as you see it appear, because once they've all been claimed, well, they've all been claimed.
