  • PremiumPress – Coupon Theme Review

    I purchased the VIP Club membership in PremiumPress, so i have access to all of their themes. Initially i was interested with their Auction Theme, which i need for my project. But i saw that their other themes looked good too, so i bought the bundle package.

    Now i will review their coupon theme. As side note, i also have tried to install their auction theme.
    Installing the theme is easy. But at the first time of the installation, you will be asked to import dummy data.

    I suggest you to import the dummy data so that your theme will be filled up with the default setting which is close to the theme live demo. I initially tried to not install the dummy data, and i was very confused because the theme has lot of panels, and setting pages 😀
