What a great idea! Pack a shoebox (I saw that you could use clear, plastic shoe boxes around 88 cents each at Walmart) with gifts for a certain age male or female child. Print a shipping label from their site, attach to your box and drop off your shoe box at a donation site (find by zipcode on their website). Then, you can track online exactly where your package went!
Look at their website for details on how to pack a box. Samaritan's Purse
