Force Default Variable

The main purpose of this plugin is to help increase the sales of your online store.

This plugin helps you in two ways:
1. When you set the default variable for the product and now that default variable is out of stock.
2. When you do not set a default for all or some of the variable products.

In the first case, it helps you to never have the default variable out of stock.
The second case helps you to automatically set a default variable for products with different modes (lower price variable, higher price variable, position-based, ID-based) for products.

This can all be changed via the WooCommerce -> Settings -> Default Variable menu. If you have already set a default variable for each individual product, you can decide to keep that, or use this plugin instead.
