We scored Jersey Boy tickets for $67, which included the $2 discount from the coupons found online (you MUST print this out ... they won't accept phone coupons) and tourist magazines. We got in line about half an hour before the 10 am opening time. You get a voucher which you exchange at the box office for seat assignments.
I was going to buy at ticketsatwork.com (employer sponsored) but would have paid $68 plus tax (vs. the $67 all inclusive). With ticketsatwork, you can pick your seats ahead of time, so there is value add for this source too.
You will wait in line for awhile but there is an employee who checks on your desired ticket availability while waiting so you won't waste your time. The people there are very nice. The experience was good.
