Mail service to deployed soldiers is not good. The Army does not provide address updates and it seems that mail is only occasionally forwarded.
What you can send to soldiers:
Personal Hygiene: Toothpaste, toothbrush, floss, mouth wash, soap, shampoo, deodorant, hand sanitizer, baby wipes, disposable razors, shaving cream, bug spray (NO AEROSOL CANS or GLASS BOTTLES, please).
A note for business and vacation travelers: the motel/hotel personal hygiene supplies you collect are particularly helpful for soldiers. Notepads, envelopes and simple stationary also are helpful.
Other soldier requests can range from more candy and snack foods to stuffed animals and other gifts for Afghan children.
Food, Drinks and ‘other’ stuff: Gatorade powder, Crystal Light powder, hot chocolate packets, dry soup packets, tea bags, instant coffee.
Snack foods: peanut butter in individual travel packages, beef jerky, trail mix, Chex mix, dried fruit, fruit rollups, fruit gummies, energy bars, granola bars, cereal bars, fig newtons, peanuts and mixed nuts (salted preferred), flavored sunflower seeds, hard pretzels, gum, hard candy, Lifesavers, mail-able cookies packed in ‘Pringles’ cans, and chocolate in the winter months (it melts in the hot summers there).
Other Stuff: Stationery, envelopes, pens, books, puzzle books (such as word finders, crossword, Sudoku), current event magazines, puzzles, board games, and decks of playing cards. A personal note from you with each package is a great starter!
Be sure to include your email and be patient if you don’t receive a response … remember, they’re busy fighting a war!
