I am a Bio student pursuing my post-graduation, and as student we always need many books for reference and study. I have been ordering from bookadda.com from last 2 years and I am extremely satisfied with their service. They have always kept up their promise and saved lot of my money. Recently I ordered a book with mydala coupon and got a huge discount.They always provide the delivery on time. They have an excellent team for customer care which has always been very kind and helpful. My experience with other e-commerce websites was not that great. So now over these years I have trust on bookadda and I hope they remain the same. Good Going BookAdda.Cheers!!!!!!!!
