Hello, I'm new here, but I just picked up some laminate. I only needed enough for the control panel, so I went to a local business that makes custom cabinets and store displays and they gave me a left over piece for free. For a different project, I got a 4x4 piece for $5 from a flooring and interior store (another left over piece from one of their projects).
If you need full sheets, call an interior design store that does counters and cabinets with laminate, and they can order whatever color their laminate supplier offers. If the first place you call doesn't work with laminate, just ask for a referral - that's how I got the free piece. And make sure you ask to look through their cut offs and left overs, you might find what you need at a great price.
