Hello,
01. Use product variations with an attribute like “Packaging” (“With Tin” / “Without Tin”) and set different prices for each. This lets customers choose and see the price change accordingly.
Go to Products > Attributes > Add a new attribute called Packaging > Add terms like:
With Tin
Without Tin
Edit your product, or create a new one.
Under Product data, select Variable product and add the variations. You can also set stock and images per variation.
Here is the guide on how to create variable products: https://woocommerce.com/document/variable-product/
02. You can try the following steps to adjust or remove the Google Pay button:
Go to WooCommerce > Settings > Payments > Stripe.
Click the Manage button. https://prnt.sc/7B1Pr4d8As3V
Scroll to Google Pay and click Customize — here you can change the button’s size or disable it if needed.
Best Regards,
