If you buy something not in a physical store but at a distance, in many cases you as a customer have the right to cancel the purchase within 14 days without reason. This allows you to check at home whether the product meets your expectations. This is the legal right of withdrawal.
Note: The right of withdrawal does not apply at: public auctions and bankruptcy and foreclosure auctions.
If you are a business customer, the right of withdrawal does not apply. You can find more information about the legal right of withdrawal in the auction information.
