As president of the 2008 school graduation, im making an activity at a Bowling center to make money for our class day, we already have the contract on the bowling center, so, we have to seel 100 tickets for the activity, the Bowling center told me i have full acces to the microphone, i can promocionate stores there, so the question is, is it possible to sell tickets to them, and promocionate them in the Bowling center, i have the idea, and asuming the ddo buy tickets, a part of the money they give us will be used to buy a gift card on the store and raffle it. Is it possible to do that in a store?
