That is a good way of looking at Deecey. You can also sell directly from your website and have 100% provits but if you only sell three items, you only earn $30. If you are going to make money, you have to treat this as a business. If I were a merchant (and I'm not), I'd do tests in different markets and see which produces the best results for me. And, remember, customers get into ruts they hate to break. I have four sites from which I buy almost weekly...given my personal habits, it would take something very, very interesting for me to shop elsewhere (though I will, if something is a good enough buy or unique or if I have a good relationship with a particular merchant). I might be unusual in that respect, but I doubt it.
