How to set shipping rates based on product quantity?

I have seen this question asked by quite a few people, but I haven’t seen a great solution yet.

The store I am working on needs an app to create shipping rates but product quantity.

For example:

6 bottles=$35 shipping

12 bottles=$50 shipping

24 bottles= $75 shipping

etc…

I have tried doing this by weight BUT the store is connected to a POS system API and there is no way to keep it from over-writing the product weight field back to zero (so they would have to add the weights on their 2000+ products at the store level and that is a no-go).

Alternately, is there something that would set a static weight for ALL products (and wouldn’t be impacted by the POS system updates)?

Thank you!

Hi @MuseDesign ,

Just to confirm; do you ship the bottles as a set of 6?

If yes, you can use our Multi Carrier Shipping Label app that allows you to set rates based on product quantity. You can create quantity-based flat rates so that, when your customer orders 6 bottles, the shipping rate is $35; for 12 bottles, the shipping rate is $50; and so on.

Thank you everyone for the suggestions!

I ended up using Advanced Shipping Rules and it seems to be meeting my needs.
