The pricing was very great, especially so since I had activated my Amazon Prime trial in order to get free shipping (I managed to get it for $138.40, if I were to purchase it locally it would cost $199.99). The order arrived in 13 days. The items gave much needed information which I was unable to glean from online sources and allow me to lend the rulebooks to others for use. I should mention that the item did not come with any form of protective packaging, it was left to bounce around inside the box.
The Player's Handbook occasionally suffered from some very slight blurring on some headings, aside from this I have found no issues.
The Dungeon Master's Guide was actually in very poor condition, the binding was flush with the bottom of the cover rather than being centred (this caused rubbing if inserted into the accompanying case or a bookshelf); the fabric spine of the book stuck out and was not secured at the bottom; headings suffer the same issue as the Player's Handbook; the book has a black stain on the bottom (most likely caused by rubbing against the case); the last few pages have been dented and the last-most page has a small tear; the cover has an indentation, it looks to have been caused by a price tag that was there previously.
The Monster Manual came in perfect condition and I have no issues with it.
The Dungeon Master's Screen was in acceptable condition, although there was some slight creasing in the paper layer at the foldable sections.
The slipcase was actually surprisingly useful. I almost always carry around my items to my D&D events so having the option to restrain them together is a great option to have. The carboard it's made of is also fairly stiff so it is also fairly protective.
EDIT: After a couple of month I have noticed that all the items are prone to two things; crumpling and rubbing.
The paper covers were all about half a centimeter off from the actual book, this caused it to easily and irreversibly crumple under light pressure.
The paper covers were also susceptible when rubbed against other objects (including the other items when placed inside of, and retrieved from the slipcase. This caused the items to gain several blurred and grey splotches scattered across them. I have markings from inside the slipcase from the books rubbing against it.
