Price is fair and honestly affordable for all BSFL participants, I really put a lot of effort in making unique logos with personal touch of details.
I am already thinking what would suit you good based on your feedback and history in bitcointalk forum.

You can use them anyway you like.
Main purpose should be to add them in standings table, in the same way like we see in Premier League, La Liga and other leagues.
They can also be used pre match and post match for most interesting matches, or for previews.
