Getting care packages from abroad

hey! has anyone ever gotten any care packages sent to them from the states?  when i lived in rio they managed to all make it to my apartment safe and sound and to my surprise tax free... i just moved to bsas and was wondering if it would be safe to get stuff mailed here....

Expect presents to be opened and letters likewise. Do not send anything that you will miss if it doesn't arrive. Expect registered postal items to be subjected to tax when they arrive. Expect a huge delay in receiving to Argentina, not so much the other direction.

sad news, but thanks for the reply!
