There is no PX. You pay for your health care and have to submit for reinbursement. But you can have a great life and live better then in the US. Depending on what you need.
There are a few here if you included retired for medical purposes too. I get a monthlt stipend for a back injusry and it covers the phone bill and my daughters monthly tuition.
If you retired w/20 years like my brother you probably make enough to live here comfortably - even if you have to buy a house.
Admitted to Centro Medico in POP twice in last 3 years. Both times four day stays. Hospital billed Tricare For Life both times direct. First time Tricare paid 80% and second time 75%.
