Yes you can! When you want a special combination, which is not in the list of pledges, please pledge for one instrument and add the amount of euros on top of the instruments you want in your combo.
So let's take an example: Lets say Robin Hood wants one CRD (bare circuit board), which is €49, and two DVCs, which are €99 each. He simply pledges for two DVC's (198€) and adds €49 to that pledge.
Just send us a message saying you pledged 49 euros extra for one CRD instrument and we will do the rest. No worries about shipping. We will take care of that.
