Frequently Asked Questions

What does a Mini Museum sale code typically cover?

The brand runs named sitewide codes, such as DINOSUMMER, EARLYBIRD, SEASONS and STARLIGHT, that take around 20% off most items in the shop for a fixed window. They are genuinely broad across fossils, meteorites and relics, but they do not apply to everything, and the exclusion list is published on each sale page.
 

What is excluded from Mini Museum discount codes?

Bundles, because they are already discounted, along with apparel, third party products including the Friends of Mini Museum collection, pre-orders, special offer items, anything in BackerKit, and gift cards. The discount also applies to the product total only, not to shipping, and cannot be combined with other offers.

 

How do I get free US shipping?

Free US shipping is offered during sales at a threshold that changes with each promotion, having run at $30 in one sale and $75 in others. It applies to Mini Museum products only, so third party items in the cart do not count toward it. International orders typically get a flat $5 off shipping during the same promotions rather than free delivery.
 

How does the free meteorite gift work?

During most sales, a Cosmic Campo del Cielo mini meteorite is free on orders above a stated total, commonly $50 or $75. The critical detail is that you have to add the meteorite to your cart yourself before checkout; the discount applies automatically but the item does not. It is also only available while stock lasts, with no rainchecks.
 

Can I return a discounted item?

No. Mini Museum states that all discounted Mini Museums are sold as-is with no exchanges or refunds possible. That makes a sale purchase final in a way a full-price one is not, which is the trade-off for the 20% saving.
 

What is the return policy on full-price items?

Each Mini Museum is a limited edition collectible sold as-is, and there are no exchanges. If you are unhappy, a return within 30 days of purchase is possible after contacting the company first. Refunds come as either full-value store credit or back to the original payment method minus a processing fee of roughly 2.5 to 3% charged by the payment processor. That fee also applies to order cancellations.
 

Who pays return shipping?

You do. A return label can be provided, but its cost is deducted from the refund, and original shipping costs are not refundable either. Third party and Friends of Mini Museum products are not eligible for returns or refunds at all.
 

Are the specimens genuine?

Yes, and the brand publishes an authenticity guarantee covering ethical and legal sourcing, including compliance with local mining and heritage laws. It also notes that acrylic pieces are hand-assembled, so tiny air bubbles, specimen shifts and label alignment variations occur and are not defects.
 

What happens with international duties?

For the UK, VAT is collected upfront on orders below £135, with VAT and duties due directly to HMRC above that. Everywhere else, duties and taxes are the buyer's responsibility and are not collected at checkout. Australian customers spending over 1000 AUD should expect import duties plus roughly $90 USD in handling. Refusing import charges means the item comes back and is refunded minus shipping, not reshipped.
 

What if my package is lost or damaged?

Every shipment is insured against loss and theft. Missing or damaged packages need to be reported within 120 days of the shipment date for the insurance claim to be made. Contacting the company quickly means a replacement rather than an investigation you have to wait out.

Saving Guide

The sale code is broad, but the exclusion list is where money is lost:

Mini Museum's named sale codes cover most of the shop at around 20% off, which is a strong headline. The items they do not cover are the ones people most often have in their cart by accident: bundles, apparel, gift cards, pre-orders and anything from the Friends of Mini Museum or other third party ranges. A cart holding a bundle and a fossil will discount the fossil only. Splitting third party items into a separate order also makes it easier to see whether your Mini Museum subtotal clears the free shipping line.

Bundles versus a code on separates:

Bundles are excluded from sale codes because they are already discounted. That sets up a straightforward comparison: price the bundle as listed, then price the same specimens individually with the current code applied. Depending on the sale depth, either can win. On a 20% sale the individual route frequently comes out ahead, which is not obvious when the bundle is the item being promoted.

Free shipping thresholds move between sales:

The free US shipping line has run at $30 in one promotion and $75 in others, and it only counts Mini Museum items, not third party products. Because the number changes, checking the current sale page rather than assuming last time's threshold is worth the thirty seconds. International shoppers get a flat $5 off shipping during these sales instead of free delivery, which is smaller but still applies automatically.

Claim the free meteorite yourself:

The bonus Campo del Cielo meteorite is free above a stated order value, but it has to be added to the cart manually before checkout. The discount applies on its own; the item does not appear on its own. It is a small amount of money, roughly $10, but it is money left behind on a large share of qualifying orders purely because people assume it is automatic. Stock is limited and there are no rainchecks.

Discounted purchases are final:

Full-price Mini Museums can be returned within 30 days, subject to contacting the company first and accepting either store credit at full value or a refund minus the payment processor fee. Discounted items are sold as-is with no refund or exchange. The 20% saving therefore comes with the loss of the return path, which is worth pausing on for a large showcase specimen but rarely matters for a $29 display card.

Store credit refunds are worth more than card refunds:

On an eligible return, a refund to the original payment method has roughly 2.5 to 3% deducted as the processing fee, while a store credit refund is issued at the full amount. For anyone who is likely to buy from Mini Museum again, taking the credit keeps the whole value instead of surrendering a slice to the payment processor. The same fee applies to cancellations.

Shop by price when you are gift buying:

The shop is organised into $19 and under, $29 and under, $49 and under, $69 and under, $99 and under and $100 and up. Setting the band first, then applying the sale code, keeps a gift budget intact rather than discovering that 20% off a $199 piece is still well past what you meant to spend. The lower bands hold a large number of genuine fossils and relics.

International buyers should price the duties, not just the cart:

Outside the UK, Mini Museum does not collect duties or VAT at checkout, so those arrive later and are yours to pay. Australian orders above 1000 AUD attract duties plus roughly $90 USD in handling. Refusing the charges gets the order returned and refunded minus shipping, so it is a costly way to change your mind. Brazil and India are not served at all.

Before you check out:

  • Your cart is free of bundles, apparel, gift cards, pre-orders and third party items if you want the code to apply
  • You compared the bundle price against the same items individually with the code
  • Mini Museum subtotal clears the current sale's free US shipping threshold
  • The free meteorite has been added to the cart manuallyYou accept that discounted items cannot be returned or exchanged
  • Store credit is chosen over a card refund if you will buy again, to avoid the processing fee
  • International orders account for duties, VAT and any handling fees
