Hi, I have got this link to get NameCheap's $0.98 Domain Promo although nothing is going on like this promo officially from NameCheap. Have you also tried out ??

All you have to do, click on 'Generate Code' and it will take to to Login/Sign UP page, YOU MUST SIGN UP FOR A NEW ACCOUNT and then search for the domain as usual and the other processes seem to be very easy as we buy domains from NameCheap. That Generated Coupon must be used with that Account Only. It also consists free WhoisGuard and Personal Open-Xchange Email for 1 Year. I bought a .org domain and it had no ICANN fee although registering .COM & .NET domain will add you $0.18 more as ICANN Fee.
I have no idea how long it will stay online. You may try it if you are waiting for a promo on NC. ;)
Thanks all.
