DPO Dynamic Product Options

This is the best product options app available hands down! It can do everything we have thrown at it. It takes a bit of time to get your heard around it but once you do, you realise you have only scratched the surface of its capabilities.

But, an app such as this is only as good as its support - and here is where it really shines. Roman is amazing and it seems there is nothing he can't answer or do for you in a very timely manner.

It's not the cheapest - but having tried several others, you get what you pay for (and sometimes more!)
