How much is my donation (above 100 EUR) worth? If you made a donation greater than 100 EUR early on in the project you were given a voucher equal to the donated amount when we launched our shop. This amount carry a 2% monthly interest until the day we require the full payment for the device, even if you use the provided voucher before this is asked for. If you donated 100 EUR 2013-11-01 and we ask for full payment by 2015-11-01, your donation would be worth: 148.00 EUR; 2% monthly interest from original donation * 24 (months)
The rebate amount will raise by 2% for each month between donation and start of shipment. E.g. 200 EUR entitle for 204 EUR rebate after 1 full month. This is a bonus for supporting the project upfront.
