WooCommerce Price Update
<p>I am creating a WooCommerce booking site like:</p>

<p>"On the single product page, the base price is $400, when the user chooses a date, the price will then be updated, for example the user chose December 1 which has additional $50 charge, the total price would then be $450."</p>

<p>Now, my problems/questions would be:</p>

<p>How do I retrieve the Additional Monthly price? would it be okay if it is from another table on MySQL?</p>

<p>How do I updated the price in the single product page of WooCommrce, should there be a hook that I need to use?</p>
