I did some digging around this text and found the following article: https://ipullrank.com/ecommerce-shipping-fees-organic-search
The author indicates that there’s no real solution here, and that Google has “made the decision to display this information in the SERP and shipping prices are a requirement to be visible in Google Shopping.”
The article goes on to show an example including “4-day delivery”:
In the example above, the specificity of the shipping rate has the potential to create curiosity in the user. “4-day delivery” suggests that there may be other options available at different price points. Perhaps merchants can use the transit time label as an opportunity to recapture some of the clicks that may otherwise be lost due to high shipping.
Thank you @ambergohn for finding this article! I’ll share this with my team.
