I was looking at the Melda site today and as Mettelus says, you can get the price cut from bundles with the stuff you buy on sale every week. I saw how I could save on the Mix Bundle with the few plugins I have. And to add to that, you will get off the Total or Complete bundles for any smaller bundles you get.
I am just constantly amazed at the quality of Melda's stuff. They are without a doubt some of the best out there. And I never really thought that the Multi-Band feature of a lot of their plugs was really that much a feature, but more of a gimmick. Man was I wrong. This is one of the features that set them apart.
They constantly update all the plugins and evolve them for free. Not for a version number or two. Always. You can't go wrong making an investment with them.
