Zero-G’s Vocaloid sale continues into August with an additional 10% off their July discounted prices. With the additional 10% off these are now the lowest prices that their Vocaloids have ever been!
Sonika, Prima, and Tonio are available for $79.99/£56 at their respective websites:
Leon, Lola, and Miriam are available here and are still $55.99 but now come with a $25 discount coupon for your next Zero-G purchase.
You can always keep saving for Vocaloid 3, likely the reason for this sale, but the editor should be backward compatible with all Vocaloid 2s. This sale should be good for the rest of August.
