Book Of The Month Club / Scam charges
Had built up a list of books but was not told that my former company (Zooba.com) was acquired by Book of the Month, which proceeded to scrub my list, but still charge me the monthly fees. When I asked when I might expect shipment Book of the Month said they would only ship the next book free, but that I would not get any credit for the several months they were charging me.
In effect, it doesn't matter if you build your reading list. Book of the Month may delete the whole thing in order to rack up more monthly fees for themselves. Unless you are very vigilant by the time you realize you haven't been sent your regular shipment you have already been charged for the book, and guess what: no refunds, no filling any previously-made charges with a new book you might find. You are completely at their mercy.
