You had me going there for a minute, but I don't think they sell to the public and free is still alot cheaper if you do not need official charts.
... "Although NOAA produces POD charts, NOAA does not sell POD charts directly to the public. Instead, POD charts are made available through NOAA's commercial partner OceanGrafix, who has retail agents located throughout the U.S. and overseas"
The electronic up to date charts for the USA are online and free. That is not the case for Belize, (or most other truly free market countries like Belize or Canada (dig dig) actually just jealous)
Yes, I see what you are saying. You are correct on the electronic version of the charts. I was comparing the prices of the traditional paper charts with print on demand charts... which had nothing to do with what you posted. My bad.
