When I was making my order at
www.r2-bike.com I got 10 Euro voucher for myself and two 5 Euro vouchers for friends. Since none of my buddies are upgrading anything atm, I'm willing to give them away so they don't get wasted. Each yields 5 Euro discount for at least 30 Euro purchase and is valid until 31.12.2015. I can give them away to two people. PM me if interested, just don't waste them please.
