I have a couple of themes from mythemeshop and the one I'm currently working with to create my site has been giving me some trouble. It's entirely possible it's me trying to get the theme to bend in ways it's not meant to bend, but anyhow. Every time I've had an issue I can't solve, I come here to the forums and get a kind, professional response to my query—usually within an hour. I've had to wait a day or more on other forums when I've had questions, so I'm very pleased with the response time.
Jitendraa and MistaPrime always give advice that works and it's why I keep coming back to mythemeshop when I need a new theme too.
