In all White Castle locations from March 30th through May 3rd, customers will be able to purchase a Puzzle Piece for $1, $3 or $5 benefitting Autism Speaks. Each purchase will include a coupon for one free Slider good for a later date. In 2013, the campaign raised $607,000 in stores from point of purchase and White Castle donated an additional $25,000 from its 24-hour Facebook campaign featuring Anthony Adams, a retired defensive lineman of the Chicago Bears. Since 2008, White Castle has raised more than $2.3 million for Autism Speaks through this campaign. Additionally, White Castle has created a novelty “Slider” scented candle with net proceeds benefitting Autism Speaks. White Castle has also been a strong supporter of their hometown Walk Now for Autism Speaks event in Columbus, OH.
