Checkout Simulator for WooCommerce helps store owners and developers preview how checkout behaves before a customer pays. Build a test cart, apply coupons, pick a shipping address, and see which shipping zone matches, available shipping methods and rates, payment methods, and cart totals – plus context when rules interact (for example, a coupon changing free-shipping eligibility).
Perfect when you want to:
<ul>
<li>Debug shipping zones and location rules without guessing from the storefront</li>
<li>Validate shipping methods and rates for a given address</li>
<li>Check coupon + shipping interactions on a realistic cart</li>
<li>See payment methods that would appear for the simulated checkout context</li>
<li>Explain “why” something matched (zone match reasoning) to support clients</li>
</ul>
How it works
<ul>
<li>Add products (search + quantity) and optional coupon codes</li>
<li>Choose a preset test address or enter country, state, and postcode manually</li>
<li>Click Simulate to run WooCommerce’s logic</li>
</ul>
<h3>Configuration</h3>
<ul>
<li>Products: Use the product search to add one or more products and set quantities. Leave empty to only look up the shipping zone and methods for the address (no cart totals).</li>
<li>Coupon codes: Enter comma-separated codes; they are applied during simulation when products are present.</li>
<li>Shipping address: Select a preset (e.g. US – California) or choose “Enter manually” and fill Country, State/County, and Postcode.</li>
<li>Access: Only users with the <code>manage_woocommerce</code> capability can open the Checkout Simulator (typically Administrators and Shop Managers).</li>
</ul>

Coupon Generator for WooCommerce

As others have noted, it might be nice if this plugin exposed a couple of additional features for bulk modification - like custom code prefixes or suffixes, or descriptions, for example - but it does just what it says, exposes at least some of those features via filter for custom development, and is bottom-line great "for the price."

Works great fresh out of the box

Great plugin, does exactly what it states and does it in a very friendly user interface. If I could add something more to it then I guess it would be an option to delete all of the generated coupons in case of an error.
Thank you for the excellent product!
