Cheaper approach to MCompleteBundle is first to buy some bundles to lower the price.
For example when I logged in my price for MCompleteBundle was 275e, I bought MMixingFXBundle for 24e and it lower the price to 98e. Then I looked what bundle have most plugins that I don`t have, it was MCreativeFXBundle (30e), after I bought it MCompleteBundle was 10e. So insted of 275e I paid 64e.
Maybe it is glitch but it worked.
