What's New on the Mystery Box Builder Pricing
The Pricing page in Mystery Box Builder has a new layout. It now shows all plans side by side with a live cost estimator, a way to contact support about a custom plan, and — for stores already on a legacy paid plan — a banner explaining what happens if you change plans.
1. App pricing update banner for legacy paid plans
If your store is already on a legacy paid plan, the Pricing page now shows an App pricing update banner above the plan list. It explains that changing your subscription plan — or downgrading and later upgrading again — switches you to current pricing; otherwise, you keep your existing pricing. Click Contact us in the banner to ask about it in the support chat.
Note: If you're on a legacy paid plan, your current price may be lower than the plans shown above — that's expected.
⚠️ Important: Changing your subscription plan — or downgrading and later re-upgrading — permanently switches your store to current pricing. There's no way to get your legacy pricing back through the UI.
2. Plan comparison
The plan comparison now shows all four plans side by side, each with its own Choose this plan button:
- Free — $0, available for testing and setup only, 10 free box sales/month.
- Nitro — $24.9/month, 100 free box sales/month.
- Booster — $114.9/month, 500 free box sales/month.
- Prime — $299.9/month, 1,500 free box sales/month, highlighted as the top plan.
Every paid plan also charges 2% of box sales (minimum $0.25 per box) once you go over its included monthly volume.
3. New "Estimate your app charge" calculator
A new Estimate your app charge card at the bottom of the Pricing page recommends a plan based on your own numbers. Enter your Average price of each box and Total monthly box volume, and it shows the recommended plan and the estimated monthly cost, including the extra per-box fee. With the default values ($10 average price, 2,000 boxes/month), it recommends Prime at an estimated $424.90/month.
The estimate updates as soon as you change either field — there's no button to click.
Entering $50 as the average price and 200 as the total monthly box volume changes the recommendation to Booster, at an estimated $114.90/month.
4. Contact us for a custom plan
If none of the plans fit your business, click Contact us in the Does our pricing not fit your business? card next to the calculator. It opens the support chat with a message already filled in: "I'd like to discuss the custom app charge plan." The Contact us link in the App pricing update banner opens the same chat.
