A percentage discount is easy to lose through small handling errors at checkout. The BitBox promo code MADTRADES takes 5% off an order at bitbox.swiss, but only if it is entered correctly, in the right field, before payment is confirmed. The mistakes below are the ones most likely to leave you paying full price.
The most expensive error is submitting the order first and hoping to add the discount afterwards. Discount fields are not editable after an order is submitted, so the 5% cannot be retro-fitted once payment has gone through. Treat the discount box as a step in the checkout sequence, not an afterthought.
The correct order is: choose your device edition and any accessories, add them to the cart, continue to checkout, enter shipping details, then enter MADTRADES in the discount/promo code field and apply it. Only after the reduction appears in the order summary should you pay.
On desktop the discount or promo code field usually sits in the right-hand order summary panel. On mobile that panel is collapsed behind a "show order summary" toggle, and shoppers who never expand it often conclude the store does not accept codes at all. Tap the toggle, scroll to the code field, and enter the code there.
Two formatting problems account for most failed entries:
Trailing spaces. Copying the code from a page or message can pick up an invisible space at the end, which causes the entry to fail. Type it manually, or delete any stray space before applying.
Assuming capitalisation matters. It does not. Case is irrelevant, so a rejection is not caused by lower-case letters. If the code fails, look for spaces or mistyped characters instead.
Enter the code with no spaces anywhere, apply it, and read the order summary rather than assuming it worked.
Applying a code and seeing a confirmation message is not the same as seeing the money come off. Before paying, check that the order summary shows a 5% reduction against the subtotal. If the figure does not change, the code has not been accepted and paying at that point means paying full price.
Remember that the discount is a percentage. It applies proportionally, so the absolute saving scales with basket size \u2014 a wallet plus a metal seed backup plate, cable or pouch will save more in cash terms than a bare device. That is a reason to consolidate a planned purchase into one order rather than splitting it.
BitBox ships internationally from Switzerland, and duties and VAT handling vary by destination country. Shipping costs and import charges are not stated in advance here, so check the checkout page for your own country before judging whether the final figure is what you expected. A 5% discount on the hardware does not necessarily offset import charges, and those charges are separate from the promo code.
Also keep in mind that only hardware is paid for. The BitBoxApp used for setup and transactions, on desktop and mobile, is free software, so there is nothing for the code to discount there.
Discount hunting should never push you towards an unofficial seller. Go to bitbox.swiss directly. Legitimate hardware wallets generate recovery words on-device and never ship with a pre-printed seed phrase; a device that arrives with one should not be used, whatever was saved on the purchase price.
