“available merchants”
I hope this doesn’t mean just Shopify Plus merchants.
For discussion I’ve created an overview post of the early access feature in the new editions board with a breakdown and links ,also in my signature for easy access 
https://community.shopify.com/post/1637156
@llopes85 , @Derek_Morin The feature is in early access so not all stores have been updated yet.
@LizzieS manual indicates the ability to join product discounts with other product discounts
@Nortski this looks to be on all plans, unlike checkout-script which let merchant create discount logic only on Plus stores
@coljung2 it’s a platform with millions of stores doing things unlike any platform before it ;
It cannot be all things to all people things take time do develop general solutions that will work for that many different businesses
It’s like when you are in the admin and want to sort Products by inventory… you can’t. Mind blowing sometimes the omissions that Shopify provides.
Inventory data is at the variant and location level not the product so that’s one reason and simple number sorting does not apply when each product can have 100 variants.
Hi Trevor, Do you know whether this has been rolled out yet? I cannot seem to find anything related to it.
I’d like to know as well. I’ve tried to enable combinations and there is no option on my site yet. I’m so excited I want to email subscribers and let them know but WHEN CAN THEY USE THIS!?!??!??!
Hi Trevor, our store is patiently waiting for this feature to be activated. Is there a timeline for us? Thanks
Any news on when this will include stores in The Netherlands? Still no sign of it here…
Will this feature be free for basic Shopify accounts? and do we have an ETA?
What is Shopify’s definition of "few?
Hi Trevor,
Please add my vote for this feature, the inability for multiple discount codes to be applied at the same time is very limiting and preventing us to implement strategies to boost average cart value in our store.
Thanks!
Hello, I’m trying to actually stop the stacking of my discount codes on my website. According to Shopify we’re unable to do this. Now only offer stackable codes.
its not available yet
Still waiting.. Any news?
It’s available for Non-Plus stores and Plus Sandbox stores. It’s not yet rolled out for Plus stores (I read about conflicts with Shopify Scripts). I would expect this to be rolled out by the end of September for Plus stores
Note: even with these new combined discounts, you cannot have 2 product discounts on the same product. What it does offer is combining an automated discount with a discount code of a different type. If two discounts conflict, automatically the higher discount is applied.
It’s not rolled out for all non-plus stores. According to the message in the official documentation it works only for some certain merchants. In which way these merchants were chosen - nobody knows…
Hi TrendX,
Shopify checkout is totally controlled by Shopify where we can’t make any changes or combine multiple discounts. You have to offer discounts on the cart page.
These apps will allow customers to set up discount field on the cart page as well as enter customized discount codes before checkout which will lead to increased sales and customer loyalty.
There is ABSOLUTELY no date in place for this option to regular accounts yet. You cant even get accepted for the early roll-out. They have been telling us this has been coming for almost 4 months now! This if F’ing ridiculous.
Hang in there, it will be worth it 
I have it now! Shopify Plan. Canada.
