If you click on your top link and then click on this [url=https://www.walmart.ca/search?q=thompson%27s+waterseal&x=1]link.[/url], it is small and right below the reduced price box, it takes you to a page where both products are shown. They both have the same product number #21802. I think they are the same product and one is just an older package.
