Here’s how to limit your WooCommerce Cart to just one product at a time.
This simple solution can be used for many applications. For example, your store may only allow to buy one subscription at a time.
On this same website, for example, customers can only purchase one product at a time so it’s easier for me to manage invoicing and payments, given that I switch PayPal and Stripe accounts based on what’s inside the cart.
Here’s the quick fix – enjoy!
