So I have four POD t-shirt designs listed on my site. Say I wanted to offer all four of them as a bundle, how would I go about doing that?
Normally if a customer buys a t-shirt, it triggers my POD provider to make and ship that one shirt.
However if I create a product listing for a 4-pack of shirts (each their own design), how can I trigger my POD provider to make and ship those 4 shirts from that one order.
I use SPOD as my POD provider.
If you need to trigger actions based on product purchase , or track inventory don't over complicate things just add all of the items to the cart.
Use either a separate empty "free" product as the container, or use a collection.
There are many ways to do this if the products are all predefined simplest is making a permalink(note makes a new separate session)
Also an order form customization is similar.
Contact me if you need a consult,proof of concept made, or the customization for your store to use bundling @ email@example.com
