Our store basically sells 6 month and annual subscriptions to our businesses website.
I was wondering if there was a way to make it so that they can only add one subscription (product) to the cart, not multiples, so customers don't make the mistake of buying double subscriptions.
I know you can limit the number of each individual products than can be added to the cart in the inventory tab but that's not quite what I'm after.
So basically what I want is to limit it to one product per order, not one of each product per order. Does that make sense?
