Follow the link for a discussion on beer costs - beer in Panama is cheap and based on the dozen or so i have consumed there on a par with most and - no headaches!
Excerpt from internet site:
Another great thing about drinking local beers is that they are cheap! A returnable bottle is 35–40 cents, plus a 10 cent deposit. The bottles are 9.5 ounces. Twelve ounce cans cost about 55 cents, and are cheaper in larger supermarkets than they are in the local convenience stores.
