Priced to United States (`US`) from a cookie, not from this URL.

Follow one of these to price this same page somewhere else. They are
links rather than a pattern to build, because several agent runtimes only
fetch a URL they have already read in a document:

- [United Kingdom](https://supplyvision.app/product/20979-g-shock-ga-100-1a4er-watch-black.md?destination=GB)
- [Germany](https://supplyvision.app/product/20979-g-shock-ga-100-1a4er-watch-black.md?destination=DE)
- [Poland](https://supplyvision.app/product/20979-g-shock-ga-100-1a4er-watch-black.md?destination=PL)
- [Japan](https://supplyvision.app/product/20979-g-shock-ga-100-1a4er-watch-black.md?destination=JP)

Any ISO 3166 alpha-2 code works in `?destination=`, and `?currency=` sets the currency. Both are read from the URL, so no cookie or session is needed. If the country above is not the one you asked for, your fetcher dropped the query string and every total here is for the wrong place.
