My son is being deployed soon and I want to send boxes to him. How soon do you send the boxes and how often do you send them. I'm not sure how long it will take for him to get my boxes so I didn't know if you need to send several boxes at a time or every other week?? I need advise from someone that has already done this. Any information you can give me will be helpful and thank you in advance. Also I have been collecting different kinds of food, are there any suggestions on what to send? I know they are n limited on space. One thing he has requested was sunflower seeds. He said it helps them stay awake.
