I wanted to buy an ingame item and saw wowitems.net ad on Google. They showed me the item first to prove they have it in stock so I bought it with confidence. They transferred it to my server in 2 hours and did let me stay on the live chat during the process.
I bought two cd keys from them and all worked. But third time they asked my ID photo so I sent them because they are cheap and reliable. 4 Stars because of that ID verification thing.
