Differentiation in shipping costs

I find out that the variations in handling the shipping cost do not serve our needs.

There are a couple of possibilities I would like to be able to use.

1. If a customer orders a couple of smaller products that can be shipped at once, I want the shipping costs to be for the one (larger) parcel, say €12.95. And not 5 * €6.95.

2. I want customers to be able to choose between various ways of shipping. For example with or without a signature by the receiver.

Or shipping or picking off.

These are thing I see a lot in other shops and this would really add up to the value of Marketpress.

Tnx so far,
