Where to order..
 

Parts stores are ridiculously overpriced. Where would ya'll recommended I order color matched GM paint and clear coat from?
http://www.automotivetouchup.com/spray_paint.asp is my only good lead so far.

I have used them 3 times so far this year. I would give them 2 thumbs up. Accurate color match.

Also recommend them. :)

It's that or a 6pack of dupli color match. I feel like thats the better deal, how many cans you guys think I should have on hand for a trunk lid, spoiler, and front bumper? 3 or 4 maybe? I almost want to try a can from autozone to see, covering the silver will be a pitta though.
Input on doing the inside of the trunk black? The spoiler will be matched to the car to.

If you buy from Advance Auto parts and use coupons online (so it's an online order) and choose pick up in store, you can get a nice discount. Might match that website you linked.

the dealer had good prices last time i got some years ago

When I redid my trunk to get rid of the little rust and the paint that taking the decals took off, I went to Sherwin Williams Automotive paint. Its a good match and it wasn't to expensive from what I remember.
