""It is called Favourite Super Market in Kayzer Street. It is bit difficult to find as it has a small entrance. Anyone will show the place if asked. Go to the first floor. In the ground floor you will see a hell lot of clothing shops. Enter the building and turn right there is a stare case to 1st floor. In the first floor there are 4 ,5 electronic item shops. You can search all the shops. I bought 2nd shop once you entered to the 1st floor. 2458895. As these are whole sale shops always a hell lot of people there, so they might not answer you phone calls nicely and give detailed descriptions of the items you are looking for like professional dealers. You know this is pettah.

So better visit the shop.""
