We want to by 4 tix to a celtics playoff game, and on hub stub there on sale and you can already purchase them, but the celtics don't have an official opponent yet or time or date it just says TBA, so how do get the tickets do you just wait and when the tickets are made they send them?
no you have to go and get them
I assume. I've used them a few times (StubHub), and I received the tickets the next day. I'm sure once the reg. season is over the tickets will be sent to you. You may not even need the actual tickets. Many venues allow you to print out a copy on your own printer and the paper has a bar code which they scan at the game.
