Sourcing

So I’ve ordered Ambika’s boards and enclosure and now I’m trying to source all those lovely components. I’m curious how the starter kit has all the components and boards required for one voice at such a cheap cost relative to what I’m racking up at Mouser (about $200US). Am I doing things correctly in my hunting methods? Tell me what you did or tell me this is life, so live it how it is.
Thanks

Ordering electronic components in large quantities often results in significant savings.

Yeah, I overshot what I needed where I could for a break. I paid close attention to every component’s price/quantity tiers with no massive breaks.
