Auditing book for ca final nov 2014

For auditing, consider referring to

Urvish Shah - this explains the topics well and many say it covers PM & RTPs too.

Surbhi bansal - where you refer this book, make sure you read PM & rtps also.

Both are equally good.

I want to purchase latest edition Auditing Book by Urvish Shah for CA Final NOV 2014 exam.

Please suggest me is it possible to purchase online. Please share the online link.

Thanks
