Sending a speed post through Indian Post costs around 1400 INR if it need to sent to WES or other ECA organisations
Don't send your photocopy of degrees along with your transcripts.
Firstly, your University might straightaway say "No" to this.
Secondly, putting the transcript envelope given by University in another envelope with other docs like the photocopy of degrees is a clear case of altering with University's transcript and WES will definitely think that it wasn't sent by University directly.
I know this type of arrangement seems costly but please don't waste time in reapplying/verifications in order to save money.
Hope it helps!
