On the page "Available Fields for HikaShop" on your Side if found the item: product_price (The price of the product)
The product import only hanldes a single price per product. To import multiple prices per product, use the Price import.
I have products with a price for 1 to 9 pieces with $5 and 10 to 100 pieces with $4
Can you explan me how the price import works? Is there a link to a documentation?
