Is there any software available to create website to sell my Ebook "Software testing Interview Success Kit"
Personally, I recommend you CS-CART. Don't you have money? They've got a comunity version. Now, if you can afford their professional package, great
Don't you mean a sales page in where you pre-sell your ebook/product, If so i would recommend OptimizePress for Wordpress.
Loads of themes available you can use to sell your eBook... then just download and use the PaidDownloads plugin available from wordpress that will let you sell your ebook... Its what i did...
