Snickers giving away free bags of candy. Here's how to get a treat in time for Halloween

Snickers wasn’t successful in changing the date of Halloween, but it’s still delivering on its promise to give away free candy.

Go to OneMillionSnickers.com to sign up for a gift card good for one bag of Snickers Fun Size bars worth $3.90, available through Oct. 31 or while supplies last. Giveaway times will vary.

Snickers supported the Halloween & Costume Association’s Change.org petition to move Halloween to the last Saturday of October by pledging 1 million free fun size bars if the federal government officially declared a Saturday Halloween.

The petition, also backed by Party City, has more than 150,000 signatures but after the movement faced some opposition it evolved into an additional day of celebration – National Trick or Treat Day.

“We promised a million SNICKERS, and regardless of the date, we’re going to deliver,” said Josh Olken, the candy's brand director, in a news release. “Whether fans enjoy their free SNICKERS themselves or hand them out to trick-or-treaters, we want everyone to have a satisfying Halloween.”

According to the promotion's terms, more than 55,500 gift cards will be given out at various times. A message saying "we need to refill our bowl" will be displayed when supplies run out for the day. 

There's a limit of one gift card per working cellphone number.
