Almost every night, I hit craigslist, usually after 9:00 PM. The other night an item of interest (read CHEAP) appeared about 10:30 PM, with a phone number. Being the gentleman that I am, plus my mother would have killed me for calling anyone after 9:00 PM, I waited till next morning to call. The lady told me item was sold, and picked up the night before, meaning after 10:30 PM. So exactly when is too late to call?
