In this guide, you'll find everything you need to plan a mystery box fundraiser that people will remember and want to support again.

What Is a Mystery Box Fundraiser?

A mystery box fundraiser is a fun way to raise money where people pay to get a box filled with surprise items. They won’t know what’s inside until they open it, and that’s what makes it exciting. 

Some boxes might have small prizes, and others could have something bigger. Everyone gets something, but the mystery part keeps people curious and involved.

A mystery box fundraiser works well for schools, churches, sports teams, or any group that wants to raise money in a simple and creative way. You don’t need fancy tools—just good planning and items people will enjoy.

Step 1: Set Clear Objectives

Before you start picking out items or packing boxes, take a moment to figure out your goals. 

What do you want this fundraiser to do for your nonprofit? Are you trying to raise a certain amount of money, get more community members involved, or maybe build awareness for a specific cause?

Write your goal down. Keep it simple. For example, you might say, “We want to raise $2,000 to buy supplies for our youth program” or “We hope to sell 100 boxes to support our food pantry.” 

When your team knows the goal, it’s easier to plan and stay on track.

It also helps to think about who your fundraiser is for. Are your supporters mostly families, young adults, or local businesses? Knowing your audience will help you choose mystery box item ideas that make sense and feel right for them.

Step 2: Pick a Theme That Fits Your Cause

Now that you’ve got your goals in place, it’s time to choose a theme for your mystery boxes. 

A good mystery box theme helps you stay organized and makes the whole thing more fun for buyers. It also gives people a small idea of what to expect without giving away the surprise.

Start by thinking about your cause. If you're raising money for an animal shelter, your theme could be “Pet Lovers Box” with toys, treats, or pet supplies.

Keep it simple and easy to follow. You don’t need to overthink it. Just pick a mystery box theme that connects with your audience and your mission.

You can also get creative with mystery box ideas. Try a seasonal theme like “Spring Surprise,” a color-based theme like “All Things Blue,” or something playful like “Pick Your Mood Box.” 

The theme doesn’t have to be fancy—it just needs to guide what goes into the box and make sense to your supporters.

Step 3: Decide on Pricing and Box Value

The next step is to figure out how much to charge for each box. 

Start by looking at the cost of the items going into the box. Add up what you’re spending on supplies, packaging, and any extras. Then, set a price that helps you raise money without going over your supporters’ budgets.

Offering more than one price option can be a good move. For example, you might sell small boxes for $10, medium ones for $25, and large boxes for $50. 

Make sure the items inside match the price. If someone pays more, they should feel like they got something worth it.

If you can, add a little bonus item in some boxes. It could be something small but fun, like a gift card or a local coupon. It keeps the mystery going and makes the experience more exciting for your supporters.

Step 4: Collect Donations for the Boxes

Getting items donated is a smart way to keep costs low and raise more money. Here are a few places you can ask for donations and how to approach them:

• Local businesses – Reach out to coffee shops, salons, bookstores, or small gift shops. 
• Online sellers – Try local Etsy sellers or small online shops. They might be happy to give an item in exchange for a little shoutout on your event page or social media.
• Community members – Ask board members, staff, or volunteers if they can give small new items for your mystery box fundraiser. 
• Big chain stores – Some larger stores have donation programs. You can check their websites for how to apply or visit in person with a short letter about your event.
• Local artists or crafters – These folks often enjoy getting their work seen by new people. They might donate prints, jewelry, or handmade goods.

When asking, keep it short and clear. Share what your fundraiser supports and how the donation will be used. Let them know their business will be seen by local families, and thank them no matter the response.

Step 6: Sell and Distribute the Boxes

Now, it’s time to start selling. Make it easy for people to buy and receive their mystery boxes. Keep things organized so everyone gets what they paid for and your team stays on track.

Here are a few good places to sell:

• Your nonprofit’s website 
• Online platforms 
• In-person events 
• Community spaces 
• Social media 

If this is your first time hosting such a fundraiser, consider starting with a smaller number of boxes to check interest and manage logistics effectively.

Offer contactless pickup for those who want to drive by and grab their box. Or, offer local delivery if you have volunteers who can help drop them off.

Be sure to label each box clearly. Keep a list of who ordered, how many boxes they bought, and where they need to be delivered. Staying organized helps avoid mix-ups and keeps the mystery box fundraiser running smoothly.

Step 7: Add a Fun Twist (Optional)

If you want to make your mystery box fundraiser even more fun, try adding a little surprise or game element. It’s not something you have to do, but it can help people stay excited and get more involved.

Here are a few simple ideas to try:

• Golden ticket – Hide a ticket in one of the boxes that wins an extra prize. Let buyers know there's a chance to get something special.
• Box reveal challenge – Ask buyers to share a photo or short video when they open their box. Pick one at random to win a small gift.
• Spin-the-wheel – Let people spin a small prize wheel if they buy a box at an in-person event.
• Guess what’s inside – Post a mystery box item clue on social media and let followers comment their guesses. Share the answer later.

These mystery box game ideas don’t have to cost a lot or take much time. They just give people a little more reason to take part and spread the word.

Step 8: Post-Event Engagement

Just because the mystery box fundraiser is over doesn’t mean you’re done. Staying in touch with your supporters helps keep them connected and more likely to join your next event.

Here are a few ways to keep the engagement going:

• Send thank-you emails – Let buyers know how much their support helped. Keep it short and personal.
• Share photos – Post pictures of people opening their boxes (with permission). You can also share photos of fun mystery boxes that people received.
• Ask for feedback or stories – Send a quick survey or ask people to reply with what they liked about the fundraiser. You might get some good ideas for next time.
• Invite them to your next fundraiser – Let them know what’s coming up. You don’t need a long message—just give a heads-up so they stay in the loop.

Simple follow-ups like these help build a stronger connection. It shows your nonprofit cares about more than just raising money. It also gives people a reason to stay involved, especially if you plan to run more creative fundraisers like this in the future.

Legal and Ethical Considerations

Before you launch your mystery box fundraiser, take some time to make sure everything is being done the right way. Even simple fundraisers should follow the rules and keep things fair for everyone involved.

• Keep it safe for kids – If your boxes are for families or kids, make sure the mystery box item ideas are age-appropriate and safe to use.
• Get permission for photos – If you plan to share pictures of people opening their boxes, ask first. A simple photo release form can help.
• List allergy info if needed – If your boxes include food, clearly mention if it contains nuts, dairy, or other common allergens.
• Keep records – Track donations, payments, and where each box goes. This helps with transparency and future planning.
• Be honest in your promo – Don't say the boxes are worth more than they really are. Set clear expectations about what buyers might receive.
• Use your nonprofit’s name properly – Make sure the fundraiser is clearly connected to your organization, especially if others are helping promote it.
• Respect your donors – If someone donates items for your boxes, use them as promised and give proper thanks.
