Money Saving Mom just put together a post, How You Can Help the Tornado Victims: Donate From Your Stockpile (+ more), including where you can send needed items for distribution in the Joplin area. If you have some extra items in your stockpile, this would be a great opportunity to donate them! A medium flat rate box will cost $10.95 to ship, regardless of weight. I was able to stuff quite a bit of donations into one for Alabama tornado relief (the box ended up being about 9 lbs.).
There have been a lot of natural disasters lately; continue to pray for those affected. Thank you for giving in whatever way you can.
Check out the comments on Money Saving Mom's post for additional needs, including paper plates and pet food.
