Hi,
HikaShop doesn't take into account the shipping costs for the display of the product prices on the listings of products.
So you're seeing something else.
I see that you've activated the "floating taxes" setting of your HikaShop configuration.
That means that if you display the prices without taxes on your listings, you could get a price lower than the price you entered in your product.
Maybe that's why ?
Or maybe you've configured some discount on your products and you're seeing the prices with the discounts applied ?
