where to sell your books or start your business on the side

my personal book store is at gumroad... publish there and you get fifty percent of sales. they take half and you get the rest. and its easy to upload a pdf there and a cover....
dont have a product to launch there? i also have a wholesale store for books to resell called the reseller center. you can buy the plr rights with the product you want and start selling right away...
my thanks to you for
