This is one of two kits sold in 2004 that was a collection of previously sold Harry Potter LEGO® playsets. Of the two kits that were sold in 2004, this one is the only one that combined different sets (the other one combined the large and mini versions of the Knight Bus). It was a great way for people to get multiple sets in one purchase.
I have never seen this kit listed on either Amazon or eBay but I’ve included links to both sources just in case you get lucky. However, it will be much easier for you to buy the sets that were included in this kit separately, which is why I’ve included links to each set in the description.
