Looking for a Dexter poster at any bookstore in India yielded zero results. I am a huge fan of the TV show and wanted a 2ftx3ft poster for my study. Without much hope I googled my search and to my pleasant I came across OyeBazaar.com. They had dozens of Dexter posters I could choose from. I also ended up gifting 4 posters (all below Rs.400) to my colleagues at work. I love this site. Their collection is endless.
I could spend hours browsing...
