Thank you EGOL,
Opening a store is very difficult in my niche. I am running a car reviews blog for UK and most of the advertisers are big names like Lexus, Honda, Chevrolet and so on. I was earning good income from adsense, but my account got suspended due to some issue on another blog.
I thought of multiple options and invested most of the income I earn in making the blog look and feel better for the users.
I have another idea in mind and now I am more focused (Thanks to your store idea :-)).
