Hi Lisa,
I am not sure how you may have set this up and how the categories/products set up on your website is. There are a number of ways in which this could be achieved. Can you please try the following in the Plugin’s settings:
-General > Amount limits > Minimum
-General > Amount types > Quantity
-Products > Per product category > Enable
I think it might be useful for you to separate the categories of individual wine bottles and the wine packages. Then go to the wine bottles category and set the minimum amount as 3.
In this case there would be no need to exclude any category from the minimum quantity calculations, as the limits would only apply to the wine bottles category.
Please let me know if you continue having trouble with this. In that case, would it be possible for you to share your WordPress dashboard access and we can take a look for you?
