I'm not sure how the linked helped doc addresses the question, as I'm trying to do similar type of sales option, though with PDF or hard copy available of single product.
I have tried defining "variants", but then paypal thinks that my "digital download" variant is a tangible product, and tacks on a shipping fee. So, I see that the "variants" must apply to tangible goods only.
I have read other help files as well, but none that seems to address this. If we want to make available a single product that can be purchased as DIGITAL DOWNLOAD or TANGIBLE ITEM, do we actually need to create two different items within our Admin/Store?
If not, can you please show the exact steps needed to configure everything properly?
