What to do if Google shows me a price-matching error (or similar) for my combinations?

This check applies when each combination is exported as a separate offer. Google must open a URL that preselects that combination and displays prices and availability matching the feed.

1. Use a recent module version; the anchor option is available from version 1.9.0.
2. Under Product feed management → Feed data options, check combination export and enable Include anchors in combination URLs, then save.
3. Update the feed. Copy the exact URLs of two differently priced combinations, including currency parameters and the anchor after #.
4. Open each URL in a fresh browser session. Check the selection, price, currency, availability and page structured data.

An anchor assists selection; it does not guarantee compatibility with every theme, JavaScript implementation or URL-rewriting module. If the wrong combination remains selected, ask your integrator to check that IDs and anchors survive redirects and caches. See also price-mismatch diagnosis.
