So happy I ran across this APP. Everything about it is worth every penny and more. The daily motivational reminders is priceless. It's all right here at my finger tips. I can start a letter and come back to it later to finish. We also made our travel arrangements through Sandboxx. Lowest rates we could find!
Great way to get letters to my Soldier, fast and easy!!! I love that I can send pictures and the Soldiers gets envelope, paper and stamp, one less thing for them to worry about. Thank you Sandboxx!! GREAT APP
