The plugin performs its main function – combines orders.But there is a very serious problem in the combined order: When you try to add/remove/change the quantity in this order – “Stock” does not change!

I had some issues with automating the order combining. Fahad (the developer) helped me out so much. He took the time to get on a call with me for almost an hour and everything is working perfectly now. Highly recommend the plugin because of the great functionalities and wonderful service.
