I've been pretty happy with pluginboutique.com. They usually have a good freebie every month that comes with whatever you buy from them. Last time, I got the Cherry Audio CA2600 synth for free when I bought a cheap $10 plugin. Source: over 1 year ago

There's also hundreds of youtube channels out there to help you learn how to mix, beware that some of these are adverts. Source: over 1 year ago
