Multiple shipping cost

[spc]

Hello

Now i hope someone can help me with this.
shipping cost is the main problem that prestashop have, otherwise i Think PS is the best..

Like now, i have 3 different shipping cost.

1, 69:- inkl tax
2, 200:- inkl tax
3, 595:- inkl tax

Some of the Products have the same shipping cost.
Like: 40004-3 have shipping cost 69:-
40003 have 200:-
and 10145 have 595:-

If i add one Product of the 69 the shipping is ok.
And if i add a Product with the 200 the shipping is ok.

If i have both Products the shippings is going for the higgest shipping.
And thats OK to.

But if i add 5 Products of the 69:- the shipping is going to 595:-, and thats wrong.
It shoud still be 69:-

Now i hope someone can really help me, i´m stuck right now.
And i hope someone understand what i mean.
