Hi,

I have past editions of a particular book I would like to include in my cart. A new edition is printed each year but people like to collect the series. There are 20 previous editions, all the same price but the inventory on each varies. For instance there may be 10 available of one edition and 15 of another.

Question: Do I have to set up each edition as it's own product or is there a better way? Can I use options or variants for this?

Any advice would be great!

Thanks in advance.

Joanne
