Some ideas?  You can purchase gift cards in $15 and $20 amounts that can be mailed or placed on windshields or doorsteps.  You can buy a beautiful notepad and pens, cologne or a potted plant.  There are even stores that have well made clothing for less than $20. 

Dollar Stores now carry food items that would greatly help a family in need.  Furthermore, food items can be donated to local food banks and churches.  And those great bottles of bubbles?  A wonderful gift to leave on the doorstep of a family with multiple children.

So the next time you are in a Target or Walmart, find a little gift that you think someone else would enjoy.  Then make plans to deliver the gift, anonymously!
