Newby - Product Dependencies

Hi,

What is the best way to implement product dependency:

We have 914 box seats per show, approximately 10000 total seats per show. We are selling 9000 general admission per show.

Each purchase of a box seat MUST accompany a general admission ticket.

How can we:
1. Make sure that each box seat is only valid when there is a general admission ticket?
2. Allow the web customer to let us know if they already have a complementary ticket?

Hi,

What is a complementary ticket ?

For ticket sales, you should look at HikaSerial and link your show products to packs of serials (seats):
