Just to remind you that you can be a direct seller on Amazon really easily. I have made over $250 recently - enough to buy a plane ticket to go see my ill sister and maybe a cheeseburger- listing books on Amazon. It is easy - no listing fees until you sell. And you don't have to download the pictures - for books just put in the ISBN. I could probably also sell CD's - one consideration is the weight of the package as there is a standard postage fee that Amazon charges. Actually you can sell anything: Best plan is to send out light stuff - you can do it with a better profit margin.
Books are iffy - a lot have been oversold and I don't send out much where I have hundreds of competitors and a one cent starting point. Recent college textbooks are the most successful.
Well, honestly it is easy until I have to stand in line and send it out. I know there are ways to send things out other than that - but this is not my final business plan and I haven't even explored it.
This is not revolutionary by any means, but I wanted to remind you all about this.
