There seem to be a few reports on this
Have you read the Terms and conditions of the promotion carefully to make sure the item you are buying is eligable for the offer
and that the dates of the offer are correct ?
There is usually a reason why it wont take it
If you are sure then contact ebay by going to Help and contact then put nearest to the problem in the search box or go to the bottom of the page for phone or contact
They open at 8 am weekdays
I doubt they will take any action but worth a try
