Shopify Product Network

Customers do not understand that they are placing multiple orders in one checkout. They go to one site, add products to the cart and think it is all one order. This creates confusion due to multiple charges on CC and shipping charges. Customers do not get discounts on products from other stores even though they put a discount code at checkout. If other stores mess up the order, customers do not know who to reach out for assistance.
Shopify provides very little information regarding orders and how commissions are calculated. There is very limited ability to choose what will be advertised on the site and many products are unrelated.

It's a great way to extend your reach as well as earn advertisement placement income without modifying your website. My only issue is with Collection placement. If you choose to have Network products appear in your collection they will appear in all of your collections. I would rather be able to pick and choose which collections I'm okay with other products showing up in.

It looks interesting. But there is not a lot of control or even analytics. For example, I have 3 purchases through the network, and I have the amount of commissions gained, but, what was bought, what category, how many % of this purchase I get. The main question who is paying, the other store? But in this case, since my own products also in the network, and someone could by my goods in other store, then he will receive the commission, it will be charged from me? Then how much?

So yeah, for sure there is a great opportunity, but with a bunch of questions.
