When you say "coral chips" are you refering to frags?
And what size are you expecting?
Typically frags are usually small around 1", 1 head, 5 polyps, etc...
Be a little more specific about what your looking for in terms of corals, zoos, polyps, leathers, LPS, SPS.
Then are you wanting 2" 5" 7" etc...
Help me understand what you are expecting then I can make better recommendations.
