Checking The Available To Sell Quantity At The Mint's Web Site

Here's a photo of the link for checking ATS at the Mint Web Site:

For some reason, when I copy and paste the actual link, the " Product-Variation? " portion appears in the "Preview" window, but gets truncated / vanishes when "Post New Reply" is activated. Clicking the link takes you to the USM site and a "Page Not Working" message:
https://www.usmint.gov/on/demandwar...ct-Variation
At that point, one has to add (in the browser address bar) the question mark, equals sign, and the USM Product ID code. . .as seen in the photo. . .
Save the URL to your bookmarks. . .edit the PID code as needed. Hope this helps.
