Even though Bluehost is one of the cheapest companies currently active in the hosting business they still understand that people are in need of even cheaper solutions so what they have done is circulated some bluehost coupon codes that can be used by such clients with their lower end hosting plans to further get the price down. However, such price cuts shall not impact your performance or the service you get because they provide the same service to all their customers.
Their customers in fact are happy with what they get for just $6 a month. Yes, that is the price you get after discount on shared hosting plans and it is the best that you can get in a tight budget considering that every other company shall cost more even with the shared hosting scheme chosen. However, there have been reports lately that the Bluehost service has decreased somewhat and all the price cuts are starting to show in their customer service.
