How many people use a pricing guide, like Standard Guide to Razors, 3rd ed. by Ritchie and Stewart, when buying or selling razors?
Good points to use? Bad points to use?
I am curious if it has been found by those here to be a reliable way to price. It seems to me after reading three different "guides" that it may or may not actually help in our current market place. I was going to see if it worked for some of the models that are going well (big old wedges), but thought I would ask all of you for your experience along the way.
