20% Kindle Promo can still work to purchas MBA's
Seems like Amazon has dropped the price of the 13/i5/256 to 1549.99. Might be worth a shot to price match for some of you that have ordered this and still haven't shipped.
Yes they did! Here's the link:
Apple Macbook Air MC966LL/A 13.3-Inch Laptop (NEWEST VERSION) However, they are still on Back Order.
Today, I managed to order it and using my 20% Kindle Promo Coupon. I was rejected 4 times last week using the Chat and this time I decided to use the phone method. My Amazon CSR was Rodrick. He did check to see if my Kindle was registered, which it was then applied the 20% while the MBA was in my shopping cart. He told me to refresh the page and it would show up. It worked!

I also applied the Kindle $5 coupon with purchases > $10 @ Amazon.com.
Here's how the invoice looks like.
