**We update our store regularly. However, there is always a possibility that (A) there is a price change, or (B) the ordered item(s) marked “available” are NOT available. In such cases, we have a friendly policy:
(A) The price of the ordered book may go up (by the publishers), in that case you will get the book at 15% discount (additional (15-12)% = 3% discount) on the current print price. And if it turns out that you still need to pay some more money, your cooperation is desirable.
(B) The book you ordered may not be available at this time, in that case you can ask for a full refund, or you might buy another book at 15% discount on the print price.
