I've ordered from this company a couple of times. They sell new books, but some are remainders. Great online store with great deals. This is a handy place to buy sheet music and piano books online. They have a large selection.
Audio books are so handy.
The History Channel has some of the best videos around. Their quality is unsurpassed. They can cover a history topic in ways that books never can. I love the History Channel' productions. Visit The History Channel's online store.
