Hi
I have currently set shipping(P&P) to the Per item Option, the problem is it is ok if 1,2 or 3 items are bought , but it mounts up when more are bought, ideally i would like to offer small discounts for the more items that are bought .
Here is a small example of what i have now.
1 item £2.49
2 items£4.98
3 items £7.47
And so on.

What i would like to do it something like this
1 item £2.49 P7P
2 items 2x £2.49 each P&P
3 items 3x £2.29 each P&P
4 items 4x £2.00 each P&P
5 items 5x £1.90 each P&P
So the more bought the better the shipping(P&P)
I could go by weight but it would be a nightmare weighing everythjing i get
Can anyone please tell me how i can do this please.
