Thanks! I saved the post too. Very helpful. I think I found the same rings as #2 with faster shipping and free Prime shipping

Edit: Seems like the seller randomly changes, but I was able to get them with Prime delivered by Aug 9 somehow.

Edit 2: As of 7am ET Thursday, Prime link is working again. ("Only 1 left in stock - order soon.")
