Price formatting can be customised as part of the locale property on the provider that you’re using. The price formatting customised according to this article will be reflected in the price filter, number formatting of the number of results/products and in the prices in the SearchModal. You are responsible yourself for the price formatting in your productCard. The type looks as follows: 
type PriceFormatting = {
    pre_: string;
    post_: string;
    decimal_places_delimiter_: string;
    thousands_delimiter_: string;
    places_after_comma_: number | "auto";
}
The default value is: 
({
    pre_: "",
    post_: "",
    decimal_places_delimiter_: ".",
    thousands_delimiter_: ",",
    places_after_comma_: 2
})
To customise it, spread it into the locale you’re importing. Example: 
import { DepictProvider } from "@depict-ai/react-ui";
import { en } from "@depict-ai/react-ui/locales";
import { YourDisplay } from "./display-types.ts"

function App() {
  return (
    <DepictProvider<YourDisplay>
      merchant="MERCHANT_ID"
      market="MARKET"
      locale={{
        ...en,
        price_formatting_: {
          pre_: "",
          post_: "kr",
          decimal_places_delimiter_: ",",
          thousands_delimiter_: " ",
          places_after_comma_: "auto",
        },
      }}
    >
      <div className="App">...</div>
    </DepictProvider>
  );
}

export default App;
