It was a Macys exclusive color, and you can still find them at a few stores, but they go fast. Same with the Brown Ali.
There's also been a few on ebay that have popped up.

Way too much....I'd only offer what the bag was worth: $398 or less. I've seen these listed for much less. Try again in late Oct/Nov when postings usually go up.
As for the '06 vs '07 - the '06 styles had the two pockets on the front, and the '07 only has one. The '07 styles look a lot like the '06 style: 10326 which is the smaller zip top.
