Dell headset 999 offer

Dear sir/ Madam

I bought Dell inspiron small desktop 3030 last June 30th. Bought from dell online store. At the time of my purchase, dell's head set offer price was Rs. 999. But I could not afford it at that time. But now I want to buy it. So I request you to give it to me at the offer price of 999.00. So what to do if you can afford it. Believing that you will help me as your customer...

Thanks and regards
