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>

PW WooCommerce Copy Coupon

Does what it says!

You saved me about 10 clicks and 1 minute each for 90 coupons I had to setup. That is worth a 5 star review.

Did what it says it does.
Works out of the box.

Once installed, on the list of all coupons, you'll see a third option when you hover a single coupon, besides Edit and Trash there will be a Copy action.
Once copied, the new coupon will be opened so you can immediately edit the title of the coupon.

I'm a developer and have inspected the code which is neatly organized and I didn't encounter any errors/issues while running the plugin.

Excellent and simple

Simply adds a Copy button to WooCommerce coupons to make it easier to create new coupons!
