The pledge manager was closed on the 1st of July at 8 PM Central European Time so if you missed it, it won't be possible to finalize it now.
You would have to follow the Updates and see when there is going to be a reopening (we plan to have one after the initial wave is shipped). Here is a handy link for the Updates section:

Then you can either finalize your order or add more items.
Please note that the orders from the reopening will be shipped along with the other orders from the 2nd wave or as we call it the NEW stuff wave :)
