I added this template with Shopping Cart feature from wojodesign.com.
I made this template more easy to navigated, there's no specific method
to make a new post, you write and upload an image just like you did it
in ordinary template, all you have to do is just start with this code :
/////<span class="item_price">$3,000.00</span>/////You must change $3,000.00 with your own price, after that you can upload your image and write your description as usual, for better result I suggest you to upload an image first before you write an articles
