This plugin allows to easily upload a CSV file with bulk pricing for simple and variable products.
The plugin dashboard page lists all existing bulk pricing lines and allows to export them to a CSV file. 
For further help while creating the CSV lines you can export both the products list and the available roles list.
Some further customization is also possible by:
<ul>
<li>Defining if we want to use roles or completely ignore them.</li>
<li>Use the total cart quantity or the quantity by specific product on bulk calculations.</li>
<li>Enable bulk pricing for guest (not logged in) users.</li>
<li>Display product total on the product page.</li>
<li>Display an additional label next to the price defining wether it includes taxes or not.</li>
<li>Hide taxes on the product page for specific roles.</li>
<li>Debug mode which displays further information.</li>
</ul>
