Yes, purchasing extra baggage allowance through ba.com/mmb will be cheaper than purchasing it at the airport.

If you intend to have a bag all along, it is usually cheaper to buy a non-HBO fare (the standard fare before HBOs were introduced). Buying HBO, and then adding baggage, generally costs a little bit more, even when the bag is added online.
