I've previously done this with snippets placed in the footer code, but when I was looking at the reference in the docs, it has a note that this is no longer the best way to do this and points to the Custom Shipping Endpoint docs.
This doesn't seem to be quite what I want it to do, so I'm not sure if I'm missing something or not.
What I want is this:
- standard shipping cost is flat rate of $5 per order
- orders over $100 get free shipping
Is this still best to do via footer snippets or is there a better way to do this now?
