I am trying to programmatically create orders in Shopify that are made for items I sell on Wayfair. I'm having an issue with pricing though. Items on WayFair are sometimes priced higher than they are in my store. When I create the order by setting the unitPrice of the item to the Wayfair price the order gets created using the product's price as it's listed on my store, which is higher. Is there any way to override this price to a higher price?
