There are several differences between the Free and Pro versions, which we will look at in more detail.

A detailed description of the “Rules” tab can be found here.

On the “Rules” tab you can select which the rule to apply: apply all rules, apply only 1st matched rule or disable all rules.

You can choose the type of rule: exclusive or common rule. If a product has been changed by an exclusive rule, then this product ignores the other rules. Exclusive rules applied before common rules from first tab. If exclusive rule was applied to the product – nothing else can change the price of the product!

You can see examples of using the rules here and here.
