I am struggling with one thing in shipping classes and I haven't been able to find the answer on these forums.
I would like to be able to add a fixed cost per additional item in the cart.
If someone buys one item the shipping cost is £2.95
If someone buys 2 items, the cost is £3.95 (the shipping class amount plus a fixed amount for extra items)
If someone buys 3 items, the cost is £4.95 (the shipping class amount plus 2 times the fixed amount for extra items)
I hope this makes sense :?
