Avoid like the plague
After their recent change of ownership WowHD became a nightmare. Their customer service used to reply in minutes and used to go to great lengths to help you. Now they never reply at all. What is worse, the shopping process is totally insane: you see products at reasonable prices and you include them in your basket but after you do submit the order, and only when it is too late, you see you have been billed for a much higher amount. This is clearly illegal, by the way. In short, steer well clear from them.
