[LIS-Forum] Book purchase through online portals?

Dear Sirs, This is to seek the attention of the library professional fraternity concerning the issue of book purchases through online portals, such as Amazon, Flipkart, etc. Can online portals become an alternative to the conventional method of face-to- face dealing with book-suppliers/vendors/distributors/suppliers? Can large academic and research libraries rely for their major acquisition activities on online portals? Requesting informative discussion on this subject. Thanks & regards, T.
