Letsbuy 10 % off coupon for a costly cellphone purchase with pocket money.

I wanted to purchase a cellphone with my pocket money which I have been saving for a long time, but still I am short on cash for Galaxy series mobile.
I came across an offer today by ‘Born Legend’ for ‘Samsung Wave M (S7250) Metallic Silver @ Rs.10710’ which had a letsbuy.com 10% off coupon: LBCASHBACK414943bf but it was valid only till 5th Jan

So I would request if anyone has a letsbuy.com 10% of coupon then please PM it to me if its one time use only/ individual use.

If the coupon can be used unlimited times then do post it in this thread/topic for the benefit of others.

It would be very generous of you if you could help.

Thanks,
Regards.
