How to fix maps app on iphone 5?

I'm having the same problem while using maps and its really starting to piss me off. When I drop a pin on a certain location like my house, and later try to get maps to direct me to house from another location it says my home is my current location. I know this is confusing, but basically when it says "current location to destination" I select home as my destination, and it says my home is my current location. This has happened numerous times and it is very annoying! If someone could help me with that, that would be great!

Also, what are some legitimate websites to but the iPhone from, other than the apple store?
