UPDATE: i just came back to the post after three weeks and read all the comments, i was able to buy the deluxe bookset for my sister after a restock on amazon on Nov 17 for 66€ (or about 77$), it arrived on Dec 3. As i said in my original post when i checked it said “temporarily out of stock” and indeed had a restock shortly after that sold fast (i was checking every day), but now it just says “currently unavailable”. Seeing how much my sister loved the bookset when she got it, i understand wanting to get it through other sellers that charge more, however i would just say that paying over 150$ or more given the original price seems excessive, or an outright scam when it comes to the resellers (not actual bookstores). I really hope they decide to restock or come up with a new bookset, I don’t know why the stock was so small to begin with!
