Qurbaani is not about arguing with people over the price of an animal, or sending the the money away to a poor country and saying: "My Qurbaani is done"

What kind of Qurbaani is that?

If, due to circumstance, a person requests someone to perform Hajj-e-Badal on his behalf, every Mufti will say that his Hajj is complete.

However, will the person know, himself, of the experience of Tawaaf, Sa'ee, of being present in Mina, Arafat, Muzdalifah? ...No.

He will not know the taste or the experience of Hajj or the enjoyment of standing at the Raudha-e-Mubarak and sending Salaat and Salaam to Nabi [SalAllaahu Alayhi Wasallam] 

Another example, from a worldly view: If a person owns a timeshare and he sends his family to enjoy the comforts and facilities of the timeshare, but does not go himself, then they will enjoy the beautiful scenery,  the beach, the fresh air etc. and the timeshare will be used, but he, the owner, will not get the benefit of it and enjoy.

Similarly, we have to be involved with Qurbaani, and carry it out properly, in order to draw the full benefits and experience the spirit of Qurbaani. Otherwise, just sitting in a comfortable air-conditioned office and writing a cheque for one's Qurbaani is depriving oneself of the Great benefits

This is not Qurbaani.
