In terms of price, it makes exactly 0 difference whether you reserve the GVB tickets in advance online or buy them on site, in a hotel or on the tram. If you order them in advance, you just have to pick them up from GVB, which makes ordering the internet extremely pointless ;-)) unless you have the tickets sent to you.
The GVB Center itself is tip top!
