Shipping policy

Last updated: 12 October 2026

Preparation and delivery

Preparation normally takes 1–2 business days. We inform you by email of exceptional preparation delays. Estimated transit after dispatch: mainland Portugal around 3 business days; Madeira around 5; Azores 7–15; Europe 5–10; other international destinations 7–15 business days.

These are estimates, not guaranteed dates. Preparation, customs clearance, holidays and carrier disruption may add time. An estimate does not waive mandatory delivery deadlines or remedies. Contact us promptly about a delay or missing parcel.

Destinations, charges and customs

We ship using selected delivery partners. Current delivery countries: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czechia, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Poland, Portugal, Romania, Slovakia, Slovenia, Spain and Sweden. Only destinations and addresses offered at checkout are available; local or temporary service restrictions may apply. Charges appear before payment. EU orders of €75 or more qualify for free delivery, based on the eligible order value shown at checkout after discounts.

For another destination, email hello@bymathletica.com before ordering. Carrier coverage alone does not mean a destination is available in our store.

For shipments subject to customs, the recipient is responsible for lawful import requirements and duties, taxes or clearance fees not collected at checkout. We do not control these amounts. This does not shift our own legal obligations to you. If goods are returned following a delivery or customs problem, we assess the reason and any legally recoverable costs; no automatic forfeiture of the purchase price applies.

Correct delivery details

Check the address before paying. Tell us immediately if it is incorrect; an amendment is not guaranteed after processing starts. Cooperate with reasonable carrier delivery or collection instructions. Any additional re-dispatch charge caused by incorrect information is limited to legally recoverable, documented costs agreed before re-dispatch. If we supplied the wrong goods or address, we arrange correction at our expense.
