Best App for Finding Costco Gas!

I could easily just use the Google Maps app on my iphone to find the closest Costco, but this app is worth the 99 cents because it is uncluttered and it quickly tells me not only the locations of all the Costcos in America, but it also uses Blue and Red pins on the map to tell me which Costcos sell gas and which ones do not.

Improvement I would like to see...

It would be great if when I tap on the apps "Directions" button... it would give me the option to pick directions from either Google Maps, or from the Navigon and TomTom apps I already have installed on my iphone. Both Navigon and TomTom have made it very easy to integrate access to their apps into other apps.

This apps logo is ugly, I am sure the developer can do better than that!
