[ic] $0.00 shipping, and more!

[Paul Jordan]

Hi list

If anyone is having a problem making "and keeping" shipping methods that
resolve to zero, try multiplying by .0001

Interchange will recognize it as a valid number, yet keep the shipping
outcome $0.00. You will probably have to come up with some fancy scheme
based on weight, as I did. Weight is really the only feild that the user
doesn't care about, and you can kind of create item "groups" with weight
porportions.

Anyways, I thought this tidbit may come in handy for somebody. If you need
more help, and you think this type of shipping is for you, let me know.

I had to hack something, because, and maybe I am wrong, but IC doesn't have
any sort of "shipping groups". Kind of like discounting by prod_group. I
think that would be sweet. So you could base different shipping formulas to
portions of and order.
