Here’s a very simple snippet that achieves a very complex task – what if you wanted to force your Cart to charge a deposit or a fixed fee, no matter the product price?

Well, thankfully WooCommerce is pretty flexible and a lot of workarounds can be found. In this case, forcing the checkout to a fixed amount (e.g. $100) is as simple as applying a negative “cart fee” to make the total become $100.

Sounds like Japanese? Great – here’s why you’re on Business Bloomer. Copy the snippet, apply it to your test WooCommerce site and see the magic happen – without knowing anything about coding!
