Does anyone have any suggestions for a secure postal address for Expats? I'm currently using one in Chonburi (near Pattay City) and find that about every third letter / packages makes it there.

While I'm here in the US, I can send stuff FedEx, but it cost an arm and a leg to send even small envelopes or packages. I haven't experienced any problems sending stuff from Thailand back to the US. I'm due back in the Chonburi area in a few months for an extended stay and just want to make sure that things sent my way maked it to my door step.
