Its nothing new. Indiaplaza is notorious for delays & updates are non existent... They do give good discounts but their back-end & logistics suck big time. Only order books for which you can wait for or which are not very hard to find. (No exotic titles please).
I ordered 5 books & received 3+1 on time.. One of those was wrong edition. I ordered a paperback & they sent be an abridged edition pocketbook.. Their customer care is pretty hard to get through. They are always busy entertaining other customers... They also do not respond to mails. I was lucky to get through customer care last Friday & explained everything, they said they will check & call back but even till now no response from their side..
I am still waiting for the 5th book for which they always say that it will be shipped in two days or the money will be refunded... So its better to leave that discount. This was my first experience & hopefully last if my future book purchases are only impulsive & not really important...
