which is correct?

[kks_krishna]

"send a mail to EMAIL REMOVED - Send PM to This User Instead and get your copy for eBook" or send a mail to EMAIL REMOVED - Send PM to This User Instead and get your copy of eBook.

I am confused with using "of" or " for". also suggest better form the same sentence

[Anglika]

"Send an e-mail to [ADDRESS] to get your copy of [e-book]".

You are buying a copy of something.

"Send an e-mail to [ADDRESS] to ensure your order for [e-book]"

You are also buying a copy of something, but by means of an orderfor a copy
