Hi everyone, just saw this posted on the McDonald's Facebook page and thought it was worth sharing.
By going to the McDonald's Facebook App and sharing, AMEX will donate $1 to Ronald McDonald House on your behalf. If you don't want to share publicly remember you can tick the "only me" box.
Tweeting or Instagramming with the hashtag #mchappyday will result in a further $1 from each, so $3 in total if you can do all three.
At the time of posting just under $2000 has been committed by AMEX but it is capped at $50,000 so still plenty of reason to register! :)
