You can certainly bring an old Disney popcorn bucket back into the parks for use as a personal container, but you cannot get the discounted "Refill" price with it. Disney's official policy in 2026 states that discounted refills (currently around $2.25) are only valid for the length of your stay using a bucket purchased during that specific trip. Each "season" or event usually features a specific bucket design or a "refillable" sticker/chip system that allows Cast Members to verify its validity. If you bring a bucket from 2023 or even a different trip earlier in 2026, you will be required to pay the "Full Price" for popcorn (typically around $5.50–$6.50). However, many guests still bring their favorite "Specialty" or "Limited Edition" buckets (like the Figment or Alien buckets) because they are more durable and have better carrying straps than the standard disposable boxes. While you won't save money on the popcorn itself, using your favorite souvenir bucket can still be a fun way to display your Disney fandom while snacking around the parks.
