When our daughter was having her piano lessons here in our area, the teacher buys the piano books and we just give her the payment. Now that she goes to Doquesne University, we have to buy it ourselves. So when the teacher gave us the list of books that she needs, we bought them online. The seller sent us a wrong one for one of the books that we bought so we had to check out the nearby music store to buy it. Unfortunately, we didn't find it so we are waiting for them to get it as we pre-ordered them when we went there. I did however, checked this link here and found some really nice music products.
