I am trying to set up shipping rates for my low cost no tracking items ("Product A").
I would like to set all products "A" with a rate of $.50 for the first $15 worth of those products. I have figured this out and created a shipping profile.
The problem is if someone wants to buy Product "B" and have it shipped overnight and adds a Product "A" shopify will only calculate and show the lowest price option. This does not give any option for overnight or UPS or FedEx etc.
