Many event directors will order separate events for each style and set up a linked pre-registration for you to easily register for multiple styles/divisions at the same time. You will know that this is the case if you see multiple events listed after clicking the pre-register link.
Event directors with linked pre-registrations may also offer automatic multi-style or team discounts. You will see those noted in red text at the bottom of your registration. Make sure that you add all individual styles/divisions and teammates to the same invoice in order to qualify for any discounts.
Here is an example of a multi-style discount for one athlete:
Note that the first red line is regarding a team discount. It states, "You will receive a $5.00 discount per entry fee if you register 2 or more athletes." The next line reads, "If a wrestler selects more than 1 tournament at the same time, they will receive a $49.00 discount on each additional entry fee. If you do not see the discount applied immediately after adding the additional entries, the wrestler is not eligible for the discount. No refunds will be provided, so do not pay for a registration and plan to get a refund later."
Here is what happens if a teammate is added to the registration:
If an event does not have multiple TW tournaments and is allowing double bracketing in its settings, you can register for multiple styles/divisions/weight classes as long as they are on the same invoice. If you submit payment for one style/division/weight class in a single pre-reg, you will not be able to add a new invoice for the same person.
Please keep in mind that many events prohibit wrestling in more than one age division and/or weight class. Unless the groups/divisions have overlapping or no date of birth ranges, you will not be able to register for multiple divisions.
