How not to run an online store:
– First, put in a JavaScript age-checking routine that works under IE, but not under Mozilla, so that everyone using that browser is identified as being under 13, and hence not allowed to buy stuff from you. Hey, why worry about it? Proper cross-browser date handling is well-documented, but who uses Mozilla anyway?
– Next, rely on pop-up windows for some key functions, so that people with pop-up blockers enabled can’t register on your site. Again, why worry? Only communists use pop-up blockers!

(Of course, the sad thing is that I bought a watch from them anyway. after switching browsers and disabling pop-ups.)
