I got sent an email the other day with a number of premium codes for friends to use but anyone I know who would want a code already has one so they are surplus to requirements.
Here, have some Synergy promo codes!
These will give you lifetime access to Synergy for free. They just need to copy and paste the code to the purchase page to get Synergy for free.
Choose one, use it and reply here how you went. These are all I have so if you try one and it does not work, try another and see how you go. I'll try and keep an eye on them and reply when they're all gone (I can see which are used and which are not).
Enjoy.
All gone now folks. Sorry for the limited number. If I get any more some time i'll make sure to spread the love further.
