Amazon calculates a product’s star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers, and factors that establish reviewer trustworthiness.
I FINALLY own my complete set of Harry Potter books! I would definitely recommend them to anyone with love for fantasy reads. My oldest is 32yrs old and I use to buy them as they came out for him. Always had a love for the movies. Now I can finally finish all the books at my own pace. Found a roleplay sim in SL and needed to fill in a lot of gaps to be canon accurate. The seller was quick on delivery and arrived in perfect condition. All books accounted for. Look out Hogwarts! Here I come! Go Ravenclaw :D
