a!match(): quote a delivery price

Hard

A courier's website quotes a delivery price from the destination and the parcel weight in kilograms. Return the quote:

  • a weight of 0 or less, whatever the destination: "Invalid weight"
  • destination "HOME": up to 2 kg "Price: 5", up to 10 kg "Price: 9", heavier "Price: 15"
  • destination "EU": up to 2 kg "Price: 12", heavier "Price: 20"
  • any other destination: "Quote on request"

The website sends the destination exactly as the customer typed it, so "home", "Home" and "HOME" all mean the same place.

Watch out: equals compares text exactly, capital letters included, and the first condition that holds wins. A then can hold another a!match().
