how to stop Unique Discount Code for Shopify generated in klaviyo being used with other coupon codes or discounts

Hello @smcd,

Welcome to the Klaviyo Community!

That’s an odd behavior! I know by default, coupon codes cannot be combined through Shopify. What’s more, the ability to combine discount codes is actually in beta for Shopify as they’ve explained in their own Combining Discount Help Center document.

Do you happen to be using a custom checkout portal as opposed to the default Shopify one? When creating discount codes in Klaviyo, we leverage Shopify’s own coupon API which is how the coupon codes are recognized. However, if you are using a custom checkout portal as opposed to the standard checkout method provided by Shopify, I would suspect they may have their own method of handling coupon codes which may cause this combination behavior. 

An example of this would be if you generated a coupon in Klaviyo/Shopify and another coupon through your custom checkout portal. If your custom or third-party checkout portal doesn’t have a limitation on its coupon acceptance, it may accept both coupons since they’re from different sources. 

In a case like this I would recommend reaching out and speaking with your developer to investigate further or review your own tech stack to see if anything could cause this behavior. 

I hope this helps!

Hi David,

Thank you so much for reaching out. So it’s not a custom checkout just a default Shopify checkout. It does not allow another discount code to be used but it can be used on items which are on sale on the website. So we are discounting particular ranges each week from now to Christmas, this week for example we took 15% off large furniture and if someone wished they could get another 10% off with their unique discount code generated by klaviyo. I had hoped it would not be able to be used on discounted items so it there a way to stop this from happening. I know if people had to use a discount code on the weekly offer, then that would be a way around it as two discount codes cannot be used in conjunction, but we find it beneficial that the customer can see on the product page how much the item is reduced by rather than having to wait to enter a code at checkout for this to be seen. Kindest regards, Seline.

Aww I see so it would be a matter of removing them for multiple collections and keeping them say only in sale collection and exclude sale collection? If they are still under other collections it would mean the discount could still be used against them is that right? So say a lamp starts under table lamp collection but went on sale and was added to sale collection if you had the coupon codes set up to apply to every collection excluding sale collection then it could still be used unless it was removed from the original table lamp collection? I hope this is making sense, it does in my head :) Seline 

Hey @smcd,

It would really depend on how you’ve setup your collection/catalog and the coupon. However, if i’m understanding you correctly, then yes, you would be correct! If a lamp if a lamp was in both the sale collection and the table lamp collection, so long as you have the discount set to apply to all collections excluding the sale collection, it would still qualify for the discount since it’s still being identified as being in the lamp collection.

@David To 

Tried applying discount code specifically to 300+ products but received “entitled_product_ids exceeded max number” Can you tell me if you know the maximum?
