  <blockquote>
    <p>Currently Craft Commerce can not have a stock counter that covers more

    <p>If you have some plugin experience, you could get around this issue
    you described with a plugin that updates the stock of other variants
    when someone purchases a variant using the onOrderVariant event. You
    would likely need to know the relationships between SKUs for the
    different variants within your plugin, and deduct the stock from the
    related variants like so:</p>
  
  <pre><code>craft()-&gt;db-&gt;createCommand()-&gt;update('commerce_variants',
    ['stock' =&gt; new \CDbExpression('stock - :qty', [':qty' =&gt; $theQty ])],
    'id = :variantId',
    [':variantId' =&gt; $variantId]);
  </code></pre>

    events you would need to use.</p>

  <p>When creating a new product, I can set a ticket price + a total number of tickets available at this price.

  I am looking for a solution that would allow me to sell events tickets within Craft. I'm am currently making a prototype with Craft Commerce plugin for this project, but I am already facing a major problem.
  
  When creating a new product, I can set a ticket price + a total number of tickets available at this price. When using variants, I can define multiple tickets + a total of available tickets under each price. But it does not seems possible to synchronize a total number of available tickets with different price options (full price and other at reduced fare).
  
  How can I do ? Is it possible to set the total number of tickets available outside of variants, such as the variants would be only used to set the price ?
