How many people do survey's during checkout?
For the retailers that do, I think I generally ignore them as fairly bland attempts at satisfactions surveys.
I found this example refreshing. Clearly focused on the product and mission of the company. I'd also note that the way they do it takes more guts. They presented this survey DURING my order process, not after it was complete. Not sure I'm 100% on board with that approach, but I did find it different.
