Hi,
we solved the issue. I cannot fully reproduce how, but will tell you all I got:
-
the issue starts with the merchant center crawler who uses this link ending: /currency=EUR or whatever currency.
-
this selected some other country, which we do not charge tax for and therfore it showed google net prices.
-
we have the geolocation app, install it and activate the country selector. Then go to your site and look at the countries you can select. I think with th currency=eur ening, it selects the first eur country.
-
I cannot recall fully, where you can edit this list, but its in shopify settings.
Solution:
we put a country into the list, we dont even ship to (Andorra) and added a tax override of 19% (german VAT). Google now crawls andorra prices (net, but + our tax) so no price mismatch.
You should try out some countries, but if you cannot add any other british pund countries, just remove all but UK.
cheers
