Hi,
I have 2 questions. Can someone answer me ..
First question is...
When i opened my yahoo mail i saw an advertisement showing to apply
for a citicard with an 0% apr ...
when i clicked th ad, it tok me to an URL
http://citi.bridgetrack.com/usc/platinum/generic/12mos/default.htm?BTData=C02127C716D617459554A43B7A2A4ADA09B9D9D82FFF6F8F3F4CA2DF93B9&BT_TRF=99080&app=UNSOL&sc=4T3Z6PJ4&m=NYAH0K4GU0W&langId=EN&siteId=CB&B=M&BT_TX=1

and when i clicked the  APPLY button in the above url it took me to 
https://www.accountonline.com/ACQ/Apply?BT_TRF=99080&app=UNSOL&sc=4T3Z6PJ4&m=NYAH0K4GU0W&langId=EN&siteId=CB&B=M&ProspectID=66C66024A74F4600B9B0FA7AB3CE17A5

After i have submitted all the information i got a doubt whether this
is the original citibank credit card application or not. So i when
into actual citibank site the found the url to apply for credit card
as
https://www.accountonline.com/ACQ/Apply?app=UNSOL&sc=4T3Z5PE4&m=DCDF000000W&langId=EN&siteID=CB&B=M

Do both urls point to the same site. First part of both urls are
same...can the information be passed to some other place...

Had i submitted my information to a trust worthy site. 
How can some one misuse my SSN and my address and what can i do to avoid this?
What all do i need to know who has misused my identity. Can someone
please guide regarding this.

Second question is i have purchased a pizza with dominos and they have
charged some excess amount on my credit card. Why do they need to
charge excess and can i sue them?

1.  Call Citibank and ask if they received your application for the credit card.
    Explain your website concerns,  they can advise you.  Plus never
provide personal information to sites via unsolicited e-mail.

2.  If something was charged to your credit card that was unauthorized
follow your cards procedure to dispute it.

And

3.  Don't fall for that again.

overall, dont trust deals on the internet. unless u fully understand
how it benifits whoever is giving u the deal.

Well first of all if you look on the webpage after you hit the apply
button you will see the security LOCK that means the webpage is secure
and 90% its not fake
now if you click on that lock it tells you that the license is issued
by verisign wich is a company you can trust and is issued to CitiGroup
wich is CitiBank now
last thing you can do is check who owns the domain name accountonline.com
you can do that by preforming a whois lookup by going to http://www.register.com
i did it and it came back with these results:
and by the way CITICORP owns the domain so call citi bank and check on
the status of your application

"Second question is i have purchased a pizza with dominos and they have
charged some excess amount on my credit card. Why do they need to
charge excess and can i sue them?"

First, check the price list more carefully, including toppings etc.

Second, call your credit card company and ask them to mark those
charges as fraudulent.

Third, call dominos pizza and tell them they charged too much onto
your card. Mention that the charges have been marked as fraudulent. If
you let the credit card out of your sight (or ordered over the
phone?), it's possible that one of the employees noted your card
number and expiry date down, in which case Dominos will probably be
able to help you track this person and they may face charges (at the
least, they'll lose their job). You'll probably see another charge in
this case for the correct amount.

The two apply URLs look very similar. My guess is that the first one
included an affiliate ID - Citibank will send a small payment to
whoever placed that banner advertisement or sent that junk mail. The
second one is simply somebody coming from Citibank's website, so they
don't need to pay anybody.

Also, the URL begins with https:// (s for secure). This means any
computer (and hacker) along the route from yours to theirs will not be
able to read or alter the data. It also doesn't contain an @ character
- essentially, an @ character tells the browser to ignore everything
before it. Often junk mail uses this to "phish" for Paypal account
passwords:
http://paypal.com/accActive?ID=blablabla(long_string_overflowing_the_text_box_so_humans_will_not_read_next_bit)@1.54.2.3/stealPaypal.cgi

You have not fallen for some trick. :)
