If you want identification help, I suggest you post a few image(s) here and someone could identify the city or town for you. There are thousands upon thousands of cancels in various types from various regions and time periods. The vast majority are obviously going to be from the major population and business centers and will generally just be priced as a basic used stamp.
Or do you just plan to be a treasure hunter? First of all, you shouldn't depend on just one
ebay auction to determine a price for a cancel. The items at net price alongside that auction are tremendously overpriced, and the auction price is also suspect to me. If you plan to discover rare cancels, you will need to learn to identify the stamp issues and genuine cancels and will need to develop a reading knowledge of Chinese characters. There are Chinese-speaking collectors and dealers that have the jump on you. Are you prepared for doing what is needed?
