Purchased the Rich Snippets addon from these guys but I had a few queries prior to ordering. These were very quickly answered and the addon was actually slightly modified to fit our needs! The addon was quickly installed but didn't work due to conflicting code we had in the website! Again this was quickly remedied by CS Market and the addon runs flawlessly. They also as a gift ammended a small piece of css code that we required doing.
Fantastic service and would recommend to anyone!
