Integrated Sellika templates often include product price:
This is the price of the cheapest variation of this item. (Sellika uses your site's currency, so it does not matter if you use dollars or some other currency, Sellika works fine with all of them.)
If the price is updated, it will be updated in the product description as well. So, you don't need to worry that the product info in the description will be not relevant enough - in descriptions generated by Sellika, the prices will be changed in accordance with the product.
If you create your own templates, the prices will change if you used tags to add them. If you printed them manually without using tags, the text will not change automatically.
