Some merchants like Google Shopping require Value Added Tax (VAT) to be included in the price in your product feed.
In order to add VAT in price for product feed, open the advanced command box in our plugin and type:
rule discount(1.2,*)
This will increase all regular prices by 20% (ie. multiply current prices by 1.2). You can change the rate as desired.
Just as you would increase the price of the product this command will also help you to decrease the regular price of your products. Suppose you had to increase it by 20%, you would simply use:
rule discount(.80,*)
