I have a greeting card company and the shipping is configured correctly if a customer only buys one item. However if customer were to buy 2 cards they would be charged twice for shipping. Basically the zen cart is configured to charge shipping on each item $2.50 each. These cards don't weigh much and therefore my customers will be over charged for shipping these items.

Is there a way for me to customize shipping so that its configured depending on how much money a customer spends?

Here is how the well known card company, Papyrus figures out pricing:

Another option is to configure shipping according to how many cards a customer buys. Since they all weigh about the same, I can figure that a purchase of 1-4 cards costs $2.50.

THANKS FOR ANY HELP ON THIS ISSUE!!
