Autism Speaks Puzzle Pieces are now available for $1 at all White Castle restaurants as the chain kicks off its annual campaign to raise money for the research and advocacy organization.
Puzzle pieces that are purchased can be signed by customers and hung inside restaurants through the end of the campaign, which is Aug. 18. Each piece comes with a coupon for one free Slider good for a later date.
"Since White Castle has become involved with Autism Speaks, we have donated $1.3 million from the sale of puzzle pieces and the Original Slider candle," said Jamie Richardson, vice president.
Cravers purchased 384,190 puzzle pieces in 2010 and 435,000 puzzle pieces in 2011.
"Earlier this year, White Castle participated in the Autism Speaks Light it Up Blue event, where the headquarters were bathed in 40 blue spotlights to celebrate Autism Awareness in April," Richardson added. "We have the most loyal customers and they're the ones who have mainly been responsible for our donations to Autism Speaks. The success of the puzzle piece campaigns would not be possible without our loyal Cravers."
An estimated 2 million people in the U.S. are affected by autism. Scientists have yet to determine a definitive cause for the disorder.
