HELP ! A customer using 5 discount codes from 5 different brand ambassadors at checkout

[milltownbrand]

Please HELP !

I saw 1 customer today who used 5 discount codes from 5 different brand ambassadors at checkout to get x5 more of discount, on the item which was already been marked down 20% off. 

How can I limit discount code use to be only 1 per transaction ?  

(I am allowing other promo deals to combine with this ambassador discount codes. )

FYI I am using the "Affiliately" App for our brand's ambassador program.

Thank you in advance!

Hi @milltownbrand   If you are still looking for a soltuion to this, you can try using the Checkout Guardian App., which can help you with blocking the double dicount on the checkout page as a customer wont be able to checkout for already discounted products using an extra discount code, he will be shown a notification that the Discunt Codes are not applicable on already discounted products.
