We import and push orders from Woolworths MarketPlus (WMP) into Omnivore and your eCommerce Store in the exact same way as every other marketplace.
That said, with the WMP Marketplace there is an exception with orders that have more than 1 product item.
If you have an order that has more than 1 item/product, it will be sent to us an order for each item, therefore within Omnivore and your eCommerce Store you will see two orders, each with one item/product in it.
This is a WMP function, it follows the design of that marketplace order method.
Therefore if you see what 'appears' to be multiple orders, it will be because the order has more than 1 item, hence an order for each product.
