Jarre,
OMG! That's a HUGE amount of rock!! I know I'd order online if I had that much to consider!!
Economics do play a big part in all of this -- I've already put over $300 into my setup, and I already had a lot of it (it was one of my FW tanks). I'm also going to be buying a pc light setup and diving into corals, so by the time my *small* tank is done, I'm sure I'll have close to $1000 invested in it. I can't imagine the final cost of doing a large tank!!
So I guess for a small tank, hand-picking LR is best, but for a larger setup, buying bulk online is best. I'd even argue that LS is LS is LS and go with whatever's cheapest... or better yet, get play sand or aragonite and "seed" it with a little LS.
~D~
