We visited the Prop Shop in December. There wasn't a whole lot of interest in our estimation and a lot of pieces were really large. It's probably worth looking around each time you visit to see if they've added new items. It also felt like they could have put a lot more things into the shop than they had.
If you click on the "not now" button when it comes up (it's small but in the middle of the page asking you to subscribe....and then when it asks if you want a day pass), you'll be able to get to the articles. Scroll down quite a ways and the article is visible.
Hmm, then it takes you back to the sign up pages again. You'll only be able to see the photo and the first few lines of the article.
