async componentDidMount() {
    if (!GITHUB_VERSION) {
      try {
        const products = await RNIap.getProducts(itemSkus);
        // Do this just to ensure that all IAPs are available
        await RNIap.consumeAllItems();
        products.sort((a, b) => a.price.localeCompare(b.price));
        this.setState({products});
      } catch(err) {
        console.warn(err); // standardized err.code and err.message available
      }
    }
