Extracting Amazon Promo Codes - Affiliate Account

Hi, I've tried and tried, but am getting stuck on how to scrape data from a popup link. Please see attached. I have no issue extracting the data for the category, description, and dates. But scraping data from the popup "Get Link" has been a challenge. Any help would be much appreciated!
