I would just add a discount to the total bill:
Item-Qty--Rate--Amount
A----13----60----780
B----8-----40----320
C----7-----35----245
D----18----15----270
E----25----8-----200
Sub-Total = 1815
Discount = 615
Bill Amount= 1200
The discount could be another order detail line, but a special one (obviously) so that it shows up in the right place on the bill and has no inventory associated with it.
