Corrections first, everything else after.

Every page on this site is written and checked by Rami Steitieh. If something on one of them is wrong — a price that moved, a claim that no longer holds, a link that rots — say which page and what is wrong, and it will be fixed on that page with the date.

Questions and disagreements are welcome too. Nothing here is a support desk: replies take a few days, and corrections jump the queue.
