Allocating variants

[Davejaydj]

I am confused! I'm an author trying to set up Shopify to sell my 10 books as ebooks/paperbacks/audiobooks - each to be delivered by a different supplier (paperbacks will need a different US supplier to the UK one). So, I was feeling pleased with myself for setting up product variants, each with a different image. But how do I allocate the suppliers? I followed instructions from Book Vault (printers) to link their site, but that has created a duplicate listing, and I only want one for each title.

Can anyone help, please?
