The TYC concession card is $80 for 5 classes, which you can use at any time during the year. You can pay for the card with Credit card (a $3 processing fee will apply) bank deposit or with cash at TYC -once you have placed the Order and paid.  You then need to show the proof of purchase to the teacher when you go to your first class and they will write you out a card.  You present the card each each time you attend a class and the teacher will clip your card.   Make sure you hang onto the card. Lost cards will not be replaced.
