Limitations

Notice that this package is built to show "standard" categories, products and price policies. Applying "special policies" like specific prices, discounts or variable taxes can be ignored or even misunderstood by this software. In some cases vendor API and drivers do not give enough information to display some kind of data. If you are interested in displaying more data or have any questions, please contact me.
