My mother just bought a CX5 and had looked at the costco price. She ended up paying pretty close to that through a local dealership that was not part of the program. Definitely helps to know their bottom line! I actually bought my 14 brz limited a few months ago for $25,300 so $24,700 for a premium is about right. Wish I had waited a few days and gotten the 0.9% apr, though! But overall, I too was impressed how easy it was to find basically the lowest any dealerships are willing to go without doing a lot of research. Go costco!
