[wp-pro] wp e-commerce site needs quantity discounting across the board

[Sara Citrenbaum]

Here is the deal. I have a website that required Table Rate discounting
across all products.

The deal is that they sell different types of trees. The more trees you buy
(no matter which type of tree it is), the more of a discount you get. So I
basically need Table Rate Pricing across all the products, so that you can
mix and match tree types, and still get a discount.

The wp e-commerce guys don't have time to work on  it right  now. But these
were their initial thoughts...

Development Idea (should work but Im not 100% certain)
Basically the $cartitem->refresh_item() function requires slight
modifications so that the products table price condition around line 1573 in
the RC3 version:
if ($this->quantity >= $qty) {
uses the carts total quantity as opposed to the products quantity.

There may need to be additional development in other areas but I believe the
above should be a clean/valid solution.

When this initial idea was implemented though, it didn't seem to work. I'm
looking for someone who can get this to work for me.
