Is it worth to register .com domains for 10 dollars for each product you sell or get blogspot.com or wordpress.com or even googlepage.com?
If you are going to build a real website for many products, then purchase .com domain and work on your website. Or you can create blogs and wordpress websites, if you just need a landing page for a single product.
will be better if any one can give sample idea of landing page with WP blog and real website that works good
