Here's how you can send your letter to Santa and help a good cause

Here's an easy way to spread Christmas cheer: Write a letter to Santa for charity.

Now through Dec. 24, when you write a letter to Santa and send it through Macy's Believe campaign, the department store will donate $1 to the Make-A-Wish Foundation.

To participate, write a physical letter when you visit a Macy's store or go to the Believe website to write your letter online. It doesn't have to be a wish; you can also write a message of hope and Christmas cheer.

Make-A-Wish uses the money to grant wishes to kids with life-threatening medical conditions.
