So I'm trying to set up a special discount on my site.
The backstory is: Product Kits with discounts built in are cool. But you have the issue of choice vs discount -- either you add the whole kit to the cart as a bundle (and people can't swap out any of the items), or you add the pieces individually (but then they might remove some things but still get the great price on the leftover things).
So here is solution that would work for my products: base the discount on taxonomy variety. Let's say the kit would be a whole outfit -- shirt, shorts, and socks. (The people in my theoretical store wear neither shoes nor underwear.)
I set the kit to add items individually (with their full price), and then I'd like to set up a discount that works like so:
if ( some item in the cart is in the category "socks" AND
some item in the cart is in the category "shirt" AND
some item in the cart is in the category "shorts" )
then (give a 10% discount on the whole cart)Ideally, I'd like to have a bunch of those rules -- the more categories you buy from, the bigger discount you get.
I put in the discounts module, but it seems like the taxonomy rules it includes are designed to apply to one item, not the cart as a whole. Can anyone point me to where I should look to modify/create my own discount type? The whole thing looks a little overwhelming, and sadly I'm guessing that no one has trod this particular path before me.
Thanks!
Eileen
