I'd go with option B. Injecting a little JavaScript magic is always more fun than writing boring server-side code, am I right?

Option A is a bit too generic for me. A shopping cart price rule feels like overkill for a simple postcode-based adjustment.

Option D could work too. Using an observer on the event to check the postcode and modify the grand total accordingly.

Creating an observer on the event sales_quote_collect_totals_after could also work well for this scenario.

Option B sounds like a good approach. Modifying the total directly in the JavaScript file seems efficient.

Option D with the observer pattern is a good choice too. It allows you to hook into the existing event flow and update the quote data as needed.

I like option B! Modifying the JavaScript code in the checkout summary is a great way to keep the logic isolated and avoid cluttering the server-side code.

Option C seems like the most straightforward approach. Adding a custom total collector to handle the postcode-based price adjustment is a clean and modular way to implement this feature.
