Hi,
I have a site that sells funnels. We can ship 18 funnels per box for a weight of 9 lbs. Is there a way that I can tell the program that after 18 funnels, there will be an additional box weighing 9 lbs. and the same for say 54 funnels? I just got an order for 35 funnels. The freight charge says 13.65 based on 1x15 lbs. (1 box weighing 15 lbs.). The actual shipping came in at $20.00. Everything else is working fine, just don't know how to configure the shipping to take care of this problem...

thanks!
