I just purchased Events Calendar Pro and realise no that I should have just bought the Ultimate Bundle as I will need all of the plugins in the bundle.
Are you able to help me and let me know how I can convert my single purchase to the Ultimate Bundle and pay for the difference?
The cleanest way for us to handle this, due to the way Bundles are priced and put together, is for you to purchase it and then submit a refund request for the Order # of the incorrect purchase.
