Hi,
You want to use the "Post code RegEx" setting of your shipping methods to restrict them to different post codes.
For example with the regex:
#^(888[1-9]|889[0-6]|8899|916[1-3]|9166)$#
You'll only target the region with the more expensive shipping fee
Or the regex:
#^(?!88(8[1-9]|9[0-6]|99)|916[1-3]|9166)\d{4}$#
to target the rest
And you can use the min price / max price restrictions for the free shipping.
So, instead of one manual shipping method for the Netherlands, you'd have 4:
- one with the first regex and a min price of 250 and a price of 0
- one with the second regex and a min price of 100 and a price of 0
- one with the first regex and a max price of 249.999 and a price of 19
- one with the second regex and a max price of 99.999 and a price of 7.50
