Product old and new price display

Hi,

You want to create a discount via the menu Orders>Discounts.
That way, that discount will apply on the price of the product and you'll have an original price and a discounted price.
Then, you can change the "Show discounted price" to "display the price before the discount is applied" setting of the HikaShop configuration, and on the produce page of your products, you should then see both prices, with the original price being crossed.
For the listings, you can change the same option but when you edit your listings via the menu Display>Content menus/modules.

You can find the "Show discounted price" option in the Display tab of the HikaShop configuration:
www.hikashop.com/support/documentation/5...tml#display_products

And you can restrict a discount to only one product if necessary with the "products" setting of the discount:
www.hikashop.com/support/documentation/i...p-discount-form.html

Concerning the modification of the display of the elements, you can edit the file "listing_price" of the view "product" for your frontend template via the menu Display>Views of HikaShop.

Hard to say without looking at the result on your website.
