<p>Flat rate box shipping lets you define costs for boxes to different destinations. Items are packed into boxes based on item size and volume, and then that box uses the fixed costs you define per destination.</p>
<ul class="wccom-tick-list-primary">
<li>Add multiple box sizes per shipping zone.</li>
<li>Add costs per box, per weight unit, and a percentage of the item costs inside.</li>
<li>Define a cost for un-packable items e.g. too large to fit in a box.</li>
</ul>
<hr class="wccom-product-heading__hr" />
<h2>Advanced Shipping Rates using Box Packing</h2>
<p>When a customer checks out with items in their basket, the plugin reviews the destination of items, matches this to a zone, and then uses the rates in that zone for the calculation. Each destination and rate can have its own box sizes and multiple sets of box sizes, based on your shipping requirements. Items are packed into boxes to get a rate.</p>

Flat Rate Box Shipping

<p>Pack items into boxes with pre-defined costs per destination</p>

<p>Take control of your shipping costs — the simple way.</p>
