I had been spending 1-2 hours every couple days checking out all the various lists within 6 hours of our location. I missed really good listings a couple times. The bike I bought this last weekend was listed on Friday, on a list 3 hours from my town, and he had 3 calls within the first couple hours. I was the first one to show up. The app saved me the time on the computer and I was alerted immediately when the ad was placed.
I hope this hint helps someone else find a good deal!
