title: WooCommerce - Tax Calculated Incorrectly?
body: <p>I am running the latest WordPress with the latest WooCommerce, as of this writing. </p>
  
  <p>I have one standard tax rule setup for 20%. This is UK VAT.</p>
  
  <p>I have a product setup at £350. 20% of 350 should be 280. </p>
  
  <pre><code>20 x 350 / 100 = 70
  </code></pre>
  
  <p>However, on my product page AND checkout basket etc, the amount comes to: 291.67 (ex Tax). This should be 280. This is really wrong! So I'm not sure it's related to how I am coding the output of the product page, since I haven't touched the checkout template at all.</p>
  
  <p>I am not sure if I have set something up incorrectly? Why am I getting such an odd number.</p>
  
  <p>Some rules I have setup:</p>
  
  <ul>
  <li>Yes, I will enter prices inclusive of tax. </li>
  <li>Display prices during cart/checkout: Excluding tax. </li>
  <li>Shipping tax class: Shipping tax class based on cart items.</li>
  </ul>
  
  <p>I really cannot work this one out.</p>
  
  <p><strong>The tax setup:</strong></p>
