Can we sell member pricing, VIP packages, or merch?

Multiple ticket types with different prices (member, student, and so on), optional row restrictions, and perk badges at the door. Series packages and paid add-ons (merch, donations, extras) sell at checkout. Scanner redeem-at-merch-table for add-ons is not built yet — add-ons are sold and recorded on the order; fulfillment at the table is still manual. Pay-what-you-can pricing is not in the buyer flow yet.
