Samsung s860 repair?

My Dad purchased this pink s860 samsung for me only 3 months ago. Upon showing my Grandmother the camera, some way some how it slipped out my hand and hit her tile floor. The screen is not cracked but the camera WILL NOT stay on and the lens will not go back in. I'm not sure if I should:

a) send it back to samsung and pay to have it repaired
b) take it to a local camera repair store
c) or is it cheaper to buy one again off of amazon or ebay?
