Could use some creative input!
We have certain products that have common model numbers (like DVD_1, DVD_2, etc) that we would like to offer a "buy any 3" discount for. We would like to set up a way that placing any combination of 3 of these products into the cart results in a designated discount on them only (nothing else in the cart). We are thinking we could key off the model number, somehow.
Here are some caveats:
1) Because of the way the products are set up, they are not in the same category, but are spread across several.
2) If they place 1 or 2 in their cart, get no discount
3) If they place 3 in their cart, get a % discount on each
4) If they place 4 in their cart, get a % discount on only 3
5) If they place 5 in their cart, get a % discount on only 3
6) If they place 6 in their cart, get a % discount on each
Anyone have any ideas on how to work this?
Thanks
