My Clients wants her shipping to be as follows

for lets say and autograph book..
1 book is 3.95 shipping each additional book is 1.50 so like
2 books 5.45, 3 books 6.95 etc.

In reading alot of threads that come up in the searches I did , it seems like thats not possible.

So my question is , is there a way to trick the shipping to do what I want by using weight or price??

I guess like your total is 8.95 then it would cost 3.95 shipping and if your total is 17.90 it would be 5.45 shipping??

TIA!
