To put it simply, I need a quantity break / quantity discount app. I've looked on the marketplace but can't find one that suits our needs, so I'm hoping someone can help. There's a few requirements that I need:
1. it needs to work with Shopify's discount codes (or have it's own discount codes feature)
2. it can't use product variants (we use inventory tracking)
3. ideally, we'd like to be able to use the price variable in liquid (so, it can be used in operations)
I hope someone has come across something that does the above!
