Just a note of caution:
PriceSmart is normally a lot cheaper on consumer goods, but keep in mind their return policy.
Normally it is 30 days and even within these 30 days, I can say it is not always easy to get them to return non-functional goods.
This is an extra problem for us who have property there but do not live there year round.
You buy a Plasma TV, bring it to your house, use it for a few days and then go home, to come back a couple of month later. In effect this means that your warranty was 3 days

.
Not much to do about it, just stating facts.
I have bought a lot a PriceSmart and are happy with 95% of it, but specialty electronic items I sometimes buy in specialty stores instead.
But in general you have to ask all places about their warranty/return policy as it is very very different from what most of us are used to. (Where I live you have 2 years warranty on almost everything and can buy longer).)
