Kurt Willig GmbH & Co. KG reserves the right to make changes to its website and to these terms and conditions at any time. An order is always subject to the terms and conditions that are in effect at the time in which the buyer’s order is placed, unless an amendment to these conditions is required by an official directive or by law.
All declarations which affect the effectiveness of the contractual relationship or concern the modification of the contract must be made in writing, unless the parties have agreed on text form by way of exception. Post-contractual verbal arrangements with the management board of the seller are excluded from the written form clause (individually agreed terms within the meaning of Section 305 b BGB). In addition, the requirement for the written form may only be rescinded by a written agreement between the contracting parties.
