You can insert a product block with the current specials directly into a blog post, product description, or content page by using the Shortcodes feature built-into Ozcart.
Here's how:
At the place where you want the block to appear, you need to use the [view_products] short code. The code looks like this:
[view_products type="special" limit="4" img_w="200" img_h="200"]
The limit is the number of products to appear in the block, and the img_w and img_h numbers refer to the dimensions of the thumbnails in the block.
