I think i have found the cheapest domain registrar till now

OK i know godaddy provides good coupon codes and massive discounts but what about renewals. There are no coupon codes for renewals i think so. And now at renewal there prices quite high.

So i have found this registrar unlimitedgb.com which provide domain .com .net and .org only for Rs.399.

So check it now.

UPDATE

I think internet.bs is more cheaper than unlimitedgb.com
