Everything is buyer beware. It's never smart to rely solely on supposed protections offered by stores, credit cards etc. Be smart about your purchases in the first place and resort to using their help only if you absolutely need to.
I buy books from Sony & never had an issue thus far. I shop around though and check prices. Sometimes other places like Kobo, are cheaper so I buy there.
I'm curious as to which book it was you bought? Not the $0.95 one was it? Here's a copy and paste of the Overview of the book:
From Canal Boy to President or the Boyhood and Manhood of James A. Garfield
by Horatio Alger
According to Wikipedia: Horatio Alger, Jr. (January 13, 1832 ndash; July 18, 1899) was a prolific 19th-century American author whose principal output was formulaic juvenile novels that followed the adventures of bootblacks, newsboys, peddlers, buskers, and other impoverished children in their rise from humble backgrounds to lives of respectable middle-class security and comfort. His novels were hugely popular in their day. Born in Chelsea, Massachusetts, the son of a Unitarian minister, Alger entered Harvard at the age of 16. Following graduation, he briefly worked in education before touring Europe for almost a year. He then entered the Harvard Divinity School, and, in 1864, took a position at a Unitarian church in Brewster, Massachusetts. Two years later, he resigned following a pederastic scandal involving two teenage boys. He subsequently retired from the ministry entirely and moved to New York City where he formed an association with the Newsboys Lodging House and other agencies offering aid to impoverished children. His empathy for the working boys of the city, coupled with the moral values learned at home, were the basis of his many juvenile [rags to riches] novels. He died in 1899. The first Alger biography was published in 1928, and later proved to be heavily fictionalized. Other biographies followed, sometimes citing the 1928 hoax as fact. In the last decades of the twentieth century however, a few reliable biographies were published that corrected the errors and fictionalizations of the past. Many of Alger's works have been described as rags to riches stories, illustrating how down-and-out boys might be able to achieve the American Dream of wealth and success through hard work, courage, determination, and concern for others. This widely held view involves Alger's characters achieving extreme wealth and the subsequent remediation of their old ghosts. Alger is noted as a significant figure in the history of American cultural and social ideals.
Based on that I wouldn't have bought it. It doesn't tell me anything about the book. It tells me about the author and what it does tell me would make me pass. But even then, it's only $0.95.
Choose your battles. Is $0.95 really worth pursuing? Read more carefully next time.
