On the other hand, I remember those who treat me well and buy from them again and again. Their integrity or honesty pays off in the long term. I think most customers have the same attitude as me.
Even marketers with a good reputation cannot rest on their laurels. I have bought at least one product off a marketing guru with a good reputation whose product did not work for me and whose follow up help was perfunctory.
I no longer respect his reputation. I will think twice before buying anything from him again. I will certainly not sell his product to anyone else as his affiliate. If I did, I would soon lose my own reputation and my own integrity.
Of course, any one can make a mistake and sell something that appears excellent but isn't. The honest marketer will acknowledge the mistake and make amends either by refunding any money involved or by supplying a better alternative if that is preferred.
Private Label Products are currently very popular but some aspects of the Private Label phenomenon concern me. You are told gleefully that you can change the name of the product and even add your own name as if you were the creator.
What about the people who have already bought the product under its original name and then buy your version of it because they think it is a new product? They may then be refused a refund because some slight changes have been made to the original which they already have.
What about the people who have problems with the product and expect you to be able to give them answers when you may not have a clue about the source code of the product since you are not a genuine software developer?
The original developer of the product will not want to know about your troubled customers; they will have plenty of their own to deal with!
