I made my first purchase with mythemeshop after seeing their awesome e commerce demos.
Installation without any hassles
Changes to the theme can be made quickly via the theme options (general, styling, color social buttons and more)
Layouts for the e commerce themes is easy and looks really awesome
Adding sliders etc. is easy and getting the website up and running took me less then 2 hours to figure out what I needed
I needed some help with "overlapping" text on my checkout cart and David C responded with some code. I needed to expand the form and checkout boxes and David C sent me another few lines of code which allowed me to me to get the layout working the way I wanted. It all took about 2 to 3 days which was great, considering the time difference. Jitendraa also replied to my post in a short time.
The price of the themes are worth every cent and compared to other theme markets and theme developers, mythemeshop is above their competition.
