Which chips, and what kind of bulk?
For bigger bulk, someone like Cutter.com.au may work out OK, their shipping's too high for smaller orders but might be negated for the larger orders.
For smaller stuff, places like LedRise.com and IlluminationSupply.com seem to have good shipping rates, maybe leds.de as well. I know that LedRise seem to have a similar range and pricing to cutter, such as the carlco reflectors, but the shipping's a hell of a lot cheaper.
Wouldn't have a clue about 1000's etc., you're probably best off approaching the manufacturer directly then.
