The offer is back, Yahoo! is offering domain in just $ 2.99. This offer is valid till 31st october. You can register .com, .net, .org, .biz, .info, .us domains for $2.99.

Update: Now, the offer has been extended till 31st December

I wish they were also giving .in or .co.in domains and introduced this offer 20 days back because I registered my own domain 20 days back in Rs. 400( almost $9.25). Anyway, I will still buy few more domains. You can also register a domain right now.
