I've been reading around many discussion, but can't find the answer to this simple thing I want to set up. I'd prefer not to subscribe to any apps as this is 1 simple feature I need. Shopify admin feature almost offers this.
I just want to set up when a customer buys 3 or more products from certain collections they get free express shipping. I'd like to automate this, but if entering code is the the only option that'll work too.
For now I have created a code that will offer free express shipping and once entered at checkout the express shipping option becomes free. However, this applies to all collections and I can't offer express shipping for all products.
