Hi harunsk,
It depends on the city that you live in or if you can travel to the nearest big city.
If you live in or around a big city then it will ideally have a electronics market. For example, in Mumbai, Lamington road is the popular electronics market. You can go to that market and there, do some research about places to pick the cheapest products. Ideally, if you could tie up with an importer or manufacturer, then you will get the best prices.
Another possible option is to contact shops selling phones in your city and pick their dead / slow moving stock at cheap prices. On eBay, you may be able to find buyers from small towns who can buy the same products at market price, since in their locality the phone is still be in fashion.
Hope this helps!
Regards,
Sapana
