It's actually even 20 euros less with a referral code from an existing user. You (and others reading this post) can use mine if you wish (there are other codes on earlier pages). Then you can refer other new users in your turn.
My code: MELDA5785432
About the (extremely generous!) referral system:
Copy your personal referral coupon and share it with your friends. Any new customer who uses your code during checkout gets a 20 % discount for themselves and 10 % goes to you in form of credits. You can then use the credits to purchase any of our software. 1 credit = 1 EUR.
