Some people also buy books from online store please see the rating of product and check it before pay when u receive it. Beacuse lot of time some people doing lot of fraud and we dont get what we order.so be careful when u go out to buy something whetever its offline or online. And be sure u get what u order.please worth ur money before u spend it.
