I wanted to buy an alarm clock. Usually these are available only in specialised shops which sell and repair clocks and wrist watches. I tried to find one online from where I could get our local courier service to collect it for me. While I found many, I was unable to contact them on the phone to get exact specifications as I wanted one with a particular detail.
Since all the shops were quite some distance away from where I reside, I decided to ask a friend who runs a gift shop just across from my home as to whether he can suggest one in the neighbourhood.
