How Bandai's Minimum Guaranteed Allocation works

New One Piece sets are hard to get. Bandai's MGA program, which started in July 2026, is meant to make sure stores that run official prerelease events get enough product to run them. Here's how the reported formula works, a calculator you can try, and which parts are actually confirmed for US stores.

Short version: the formula people share is play product for the event plus one box per player. The math lines up with how US prereleases run, but Bandai hasn't published it, and distributors still decide what ships.

How it works, step by step

  1. 01

    Store standing

    The store registers as a Bandai TCG+ brick-and-mortar location. Its Shop Rank in TCG+, tracked separately for each game, sets how many event kits it can buy.

  2. 02

    Events booked

    The store schedules prerelease events in TCG+. The number of events and seats is what the minimum is reportedly based on.

  3. 03 · Release

    Wave 1: the floor

    First shipment is reportedly MGA only: enough packs to run the events, plus about one box per player to sell.

  4. 04 · About 4 to 6 weeks later

    Wave 2: extra stock

    A second shipment is reportedly decided by the distributor based on rank and history. It isn't guaranteed.

Store rank optional

Your store's real numbers are under My Page / Shop Rank in TCG+. Bandai doesn't publish them, so this tool doesn't guess.

Event format

Sealed events open packs at the table, so the store needs play boxes on top of the boxes it sells.

This is an estimate from community reports, not an official Bandai number. Retail value uses the $119.76 box price, not wholesale cost. Your store's actual kit count and minimums are in TCG+ under My Page / Shop Rank.

Where store rank fits in

Rank doesn't seem to add a separate bonus to the formula. It works one step earlier: rank sets how many event kits a store can buy, which limits how many events and players it can book, and that sets the floor.

What's confirmed for US stores

We checked each part of the shared formula against Bandai's official pages, US distributor terms and US store event listings.

ClaimStatusWhat we found
Play product covers 6 packs per player (4 boxes per 16 players) Consistent US OP-17 sealed events gave each player 6 packs. 16 players × 6 packs is 96 packs, which is exactly 4 boxes.
Plus one box per player to sell Reported only Comes from one store owner's post. Another store said it got 10% of its order and couldn't give each player a box.
Distributors are required to follow it Weaker than stated The wording reportedly "requests" distributors follow it. US distributor terms keep full discretion over limited products.
Based on store rank and number of events Partly confirmed Bandai says kit quantities come from Shop Rank in TCG+, and each event may require buying a minimum number of boxes.
Wave 2 arrives 4 to 6 weeks later Reported only Relayed from one store's distributor. Not published by Bandai.
Tier box caps (Standard 36 to Gold 144) Not US These come from an Italian distributor's product listing, not a US policy.

Why a store might get less

  • Distributor choice. Wave 1 can still come in under the floor, and at least one store says it did.
  • Whole cases. A store owed 40 boxes reported getting 36 because the distributor wouldn't split a case.
  • Event format. Constructed events don't open packs at the table, so there's no play-product portion.
  • Rank. A lower rank means fewer kits, which means fewer seats and a smaller floor. Newer or lower-ranked stores also tend to see less in wave 2.

How players can help their store

  • Register through TCG+. Bandai tracks store events and attendance through the app.
  • Show up and play. Bandai has said priority goes to stores that consistently support organized play.
  • Ask about box sales up front. Each store sets its own event price and box limits.
