Sometimes products that are featured on your store may not have a cost price loaded against them, and this can cause them to show on store with an unexpected sell price.
To prevent this from happening, you can choose to hide these products for each supplier on your site.
If you head into Suppliers > Edit Supplier switch "Hide 0 Cost Items" option on and we'll automatically hide products without costs for this supplier.
Simply repeat this process for each supplier you are using if needed.
