"Yeps....when it comes to communicating with your military loved one, snail mail is a thing of the past. Your love will will eventually get your letter...but you will not get one back! Sandboxx makes it so very easy for a return correspondence. My non-writing Marine sent a letter back to EVERYONE who wrote him in boot camp! OohRahh and Semper Fi! Many thanks SB!"
