I believe now that I’ve solved the mystery of the item purchased by an unknown person off my Amazon wishlist but which I never received. For some asinine reason, Amazon allows a purchaser to use a shipping address other than the one you specify for your wishlist. In other words, someone can click “add to cart” on your wishlist and then simply purchase the item for themselves instead by using their own shipping address. But when they enter in their own address, Amazon stupidly nonetheless marks the item on your wishlist as having been “purchased” for you, and so it comes off your wishlist. In other words, someone, instead of purchasing this item for themselves in the normal way, did so off of my wishlist, causing my wishlist to be incorrectly altered. At least now I can stop wondering why in the world this item never arrived. Note to anyone viewing my wishlist: Don’t do this again.
That’s happened to me before. The first time was with a Buffy DVD set. I thought I was getting it for my birthday but it never came, and I found out later someone was just buying it for themselves. I don’t know why they needed my wishlist to do so though.
