We have just implemented a great new feature.
Now you can set a % off each item. But not all items will have the same % off.. no we made it so you can set a different % off each item and with a start date and end date too!
Please make sure you have a start and end date selected for the sale to work. 

enjoy!
Any questions, bugs or errors please report them in the dedicated thread over at IWAC forums or PM us.
