I create my own coloring books and connect with Lulu for printing. I want to have two choices for my customers- coil bound or paperback. I need to know how to combine these into variants since they are the same book only with different binding. Please help. I do need to create each book so Lulu can print them - how do I put them into one listing? Thank you
A little more information -- I have created both coil bound and spiral bound books in Shopify and connected to Lulu. However, I am only able to get the spiral bound ready to print. I have the paperback as draft because if they are active then I have double the listings. I have no idea how to fix this. I appreciate your help!
