The idea alone is worth a million dollars. Being able to search CL all over the country is very useful. The only problem with this is that a lot people selling on CL dont want to accept PayPal or deal with shipping so it is kind of frustrating to finally find what you are looking for only to have to deal with one of these low tech low IQ skeptics that still exist in the world. I use it ALL the time. If youre a CL junkie like me this will be your favorite app. Ive been using it for several years now and probably havent gone a single day without searching for something.
