Note that some combinations may have a legitimate price at the end even after the coupon. Lunch on Saturday is covered for speakers and Bronze (or higher) Sponsors. Lunch on Sunday is covered for Bronze (or higher) Sponsors. T-Shirt is covered for Bronze (or higher) Sponsors and speakers. Anything beyond that is not covered.
