There's really no "trick" about it.  Every year around this time, the Augusta area Wendy's sell the Frost key tags.

Frosty key tags cost $1 and you can buy them starting November 22.  Then, just show your key tag beginning December 15 when you go to Wendy's and you get a free Junior Frosty.  Simple.

What's nice is the proceeds from the sale of the tags stay right here.  It benefits the MCG Children's Medical Center.

There are some rules.  First, you can only get the Frosty if you have made a purchase (no driving through and just getting the free Frosty).  Next, only one Junior Frosty per keytag per visit.

So far, this simple fundraiser has raised more than $40,000 and more than 250,000 free Junior Frosty's have been served!
