Is there an app I can use to create a 'product' that is just a creative that links to a special offer collection.
I.e. When a customer is browsing in the 'tops' collection, I would like a creative to show among the products called '2 for $40' that links to a collection of tops you can purchase two of for $40.
Yes, my app, BYOB can help you to do so. When you create a offer, it's shown as a product under a collection, just like your gift card.
It supports buying any x products in collection a, get a discount. So it's good for setting up 4 packs, 6 packs, etc
