I've hesitated to weigh in on the most recent discussion, since I am parting out differently from most folks participating (and differently from the question asked about parting out to keep the minifigs and defray some of the costs by selling the rest of the kit in one lump listing on eBay), BUT...
... I will just say, for anyone who might be lurking and wondering about parting out items, that if you are interested in building a slower-growth long-term business, our own model of parting out kits to sell the minifigs on eBay (and occasionally a vehicle or other desirable piece) and then building our parts store on Bricklink for "free" (with sweat equity) continues to work well for us.
It's a larger time commitment than selling figs and large segments of kits, and it requires a more detailed filing system, but I'm finding it very rewarding and our Bricklink store continues to grow pretty much with free parts, slowly but surely.
Just another option and another way to build a Lego business.
With most aspects of Lego, we're all looking at being the tortoise rather than the hare - whether it's buying and holding sets for 1 to 3 (or more) years after EOL, or building an eBay or Bricklink store "piece by piece" (ha ha).
Folks who can flip sets for fast cash are the exception, but it's not a business model I've ever been terribly good at (on a large scale, anyway), so I do my plodder thing and still make it work.
