After going through my shortcuts, I compiled a small list of articles which have helped me hone my selling skills over the years.

Tom Hopkins demonstrates the Basic Oral Close, one of the first that you should master.
Charlie Greer goes through some price objection scenarios we've all been in, and explains how to handle them.
Zig Ziglar gives a short lesson on the 3 Question Close.
These three techniques were some of the first I ever learned.
