Better Variation Price for WooCommerce allows you to replace the default price range with either the lowest or highest price. You can completely customize the text displayed for the default price.
Here are the options: 
* Display type: Choose to display the default price range, the lowest price, or the highest price 
* Display format: This gives you total control on how the price should be displayed. By default, the price will look like this: From: $ 9.90 
* Update on variation change: Update the main price with the selected variation’s price, instead of displaying a barely visible price somewhere below the description 
* Hide Reset Variations Link: Remove the clear link that appears when you select a variation

Better Variation Price for WooCommerce

Gives you complete freedom with how you display the price of your WooCommerce variable products. Replace the price range with the lowest price.

Where ever you want your ‘get’ variable to appear just type [get querystringkey].
So if your url is http://www.yoursite.com/apageorpost?thevariable=success, get the ‘success’ by typing [get thevariable] where you want it in your content.
Simple as that!
