To claim the ebay "Independence Day Promotion 2012" gift:
Visit the main ebay page at http://www.ebay.in/
Scroll the website page down and you will see the IDP 2012 Redemption banner: http://rtm.ebaystatic.com/203/RTMS/Image/930x75_strip1.jpg about midway down the website page
I cannot copy paste the link here since they use Session IDs on the page link.
If you do not see the IDP 2012 Redemption banner log out of your ebay account and close all your browser pages.
Open your browser again, preferably Internet Explorer, and visit http://www.ebay.in/
After you click on the Redemption Banner you will see the ebay website page with this:
Application Sign in - Link your eBay account to: Independence Day 2012 - Gift redemtion page
When you log in to the ebay account, you may be asked to validate your account login security and in some cases you will have to contact ebay.
Contact ebay through the online live chat link on the same page. i had a problem to log in and the live chat was from ebay australia not india. the csr validated the account login and i could then claim the gift.
Good luck
