The Merge Orders extension allows you to combine multiple customer orders so you can process and ship them as one.
<h3>Why merge orders?</h3>
The most common scenario for needing to merge orders is when you receive multiple orders for the same customer. Merging and shipping them as one package provides multiple benefits, including:
<ul>
<li>Reducing costs on shipping and packaging—better for you, and better for the planet!</li>
<li>Streamlining order processing and putting the tracking in one place.</li>
<li>Improving customer experience—they only have to track one delivery, and they receive everything they ordered at the same time.</li>
</ul>
<h3>How to merge:</h3>
Start by clicking the Merge Order button
