I'm sure these questions I'm about to ask have been answered several times on forums, but for the life of me I can't seem to find the answers to my exact questions. So sorry in advance for redundancy.
I'd like to create a product that has the option to buy a download and to buy/ship tangible media. The customer would select "download" or "audio cd" from the product detail view and it would add it to their cart with the appropriate taxes (none for downloads) and appropriate shipping settings. I'm having trouble with this for a couple of reasons.
1) I'm not sure how to create a file download that doesn't get taxed like the other product options.
2) I'm almost positive that I'm doing something wrong with the shipping modules and settings, because it tries to ship the downloads and when it tries to give a quote there is an error (this is the FedEx module currently set up correctly with the testing server info). However, it also does this with the tangible media options. I think I'm confusing the system.
What does "Product and its derivatives are shippable" mean exactly? Should this be checked or unchecked? If you were to create a product and put it in the sku, but are only selling the selected options (with their own skus), what exactly are you putting in the "weight" for when you initially create the product? I guess I'm confused as to what those first settings are for when you're creating product options.
If I'm approaching this like an oaf, please feel free to tell me, hopefully along with some info on how to do this all correctly. Thanks
