FYI... I bought some quad star from MarkerTek recently...
when you buy it online it says "what color do you want?" and it shows about 10 different colors... pick a color and the transaction goes through. Verification email comes saying "out of stock". OK, they don't actually all those colors in stock, so if you order "blue" it just gets back ordered, because you can't tell what they have, and what they don't. Call them up on the phone, and ask "what colors do you actually have?" They say "gray and black".
