Update: Feb 8th 2013: Received several PMs regarding the best possible bulk deals, there we go:
Buy over 10 (11 and above) domain and each would cost you $16.99
Buy over 20 (21 and above) domain and each would cost you $13.99
Buy over 40 (41 and above) domain and each would cost you $11.99
This will save us both time.
List is up to date as the time of this posting.
Thanks,
Rami
