In my experience, Kestrel's pricing is like Apple products. By that I mean- the price is fixed and it is what it is regardless of what retailer you purchase from. If you have a 20% discount, I'd jump on it without second thought.
Just looked and the orange one is still on sale and in stock. $635 so if you round up a 10 or 12 percent code then your looking at high fives for an elite with ab with free shipping.
