Sometimes its useful to show your prices with an attractive .99 rounding.
Making it manually on your entire catalog sounds quite impossible so we introduced the price rounding feature.
Insert the desired value (example 99) and all your products' prices will be rounded at .99
For instance, if a product price, before rounding, is equal to $23.58 it will be transformed in $23.99.
If you don't need the rounding feature anymore and you need to return to the original price, just switch it off and press "Save & Apply Rules".
