How to connect two shopify stores, with the same cart and connected offers?

[Ayman_nass]

Hi, let's suppose that I have two different connected brands, A.com and B.com, what if I want to keep the two stores on different domains but connect the stores to have the same cart, or something similar?

My goal is to create connected offers between the two stores but have the stores on different domains, how can I do this? Or is it something similar that I can do?

Thank you for your answer, but how can I share the datas and the cart between two shopify using the first option? Where can i find the options or a tutorial?

Hi, thank you but is not working. I can't see any multi store option and the link you sent is expired.

Hey @Ayman_nass 
It is possible to share cart/checkout across multiple Shopify stores as long as they are on same domain but connected to different subdomains(like example.com, a.example.com, b.example.com). Unfortunately, sharing cart across multiple domains is not possible due to some Shopify backend limitations. Please reach out if you are interested to learn more about sharing cart across multiple Shopify stores - simranjeetsingh6076@gmail.com
