Bluehost – after using several hosts over the past years, I have found Bluehost to be the most efficient and effective. Easy to work with and the most important thing, the customer service is 5 star. I have had a few issues with another account and Bluehost has been quick to respond both via live chat and their Twitter account, no problems at all.
Amazon.com – Amazon is one of the biggest marketplaces on the internet (and come to think of it probably the one of the biggest sellers in the world). The go to place for books, movies and TV series DVDs.
Book Depository – the site that I go to for most of my books, they offer a great range of books, as well as free postage to most places.
