An shopping cart plugin is very useful when it comes to set up a unique business online. Today there are more powerful and well designed e-commerce plugins for WordPress. Today every big or small business has an online presence.
Online shopping hasn’t taken off as much as developed countries like the UK or the US. However, you do have a few sites like Flipkart that are changing the face of this. Most retailers like Shoppers Stop and Big Bazaar already have online stores and Ebay has existed in India for as long as I can remember.
