My DD is now a senior...and I cannot believe how fast the past couple of years has gone. We've already made hotel reservations for graduation weekend!
But - just chiming in with a couple of ideas for care packages - that were easy-peasy to send and not all that expensive.
Cheryl's Cookies has a sampler pack (6-cookies) that you can send for about $7.

The Popcorn Factory has "popcorn greeting cards" that are inexpensive to spend that include a small sample of popcorn.

But - at this time of year - we always sent DD "1" each of every type of trick or treat candy we were giving out. Postage was not all that bad!
Now - granted - DD would always prefer something that was homemade...it just was not always easy to get that done!
