Contact your local post office and ask about the shipping rates. This way you can figure out the best shipping option.
Find out what the exact shipping address is at your child's college. Mix-ups can happen especially at larger schools, so make sure that you have the right address. The best way to find this information is by either asking your child, the college or searching the school's website.
Fill a medium-size box with various items that your child likes. Some ideas to get you started are school supplies like pencils and pens, gift cards to her favorite restaurants and stores, and toiletries including things like deodorant, toothpaste and shampoo.
Place some non-perishable food items in the box. Some ideas are beef jerky, cookies, nuts, candy bars and chips. Snacks such as these are almost always a hit with college kids.
Place any other miscellaneous items that fit your child's personal taste. Some ideas are books, DVDs, CDs and pictures.
Bring your care package to the local post office and ship the box to your child. The postmaster will weigh the box and charge you accordingly.
