The Twentieth Century Society cannot accept your order until you have paid for it in full. You may pay by MasterCard, VisaCard, Visa Debit, Visa Electron, Visa Connect, Solo.

Upon payment, the Twentieth Century Society will confirm receipt of your order by an acknowledgement displayed onscreen once your payment details have been accepted, followed by an e-mail which will be sent to the e-mail address you provide on your order details.

You will have an opportunity to check and correct any input errors in your order up until the point at which you submit your order by clicking the “next” button on the checkout page.

Your order represents an offer to us to purchase the goods which is accepted by us when we send you an e-mail confirming acceptance of your order. A legally binding contract between us is created at the point of our acceptance of your order.

The Twentieth Century Society reserves the right to choose not to accept your order for any reason, at its discretion, and will not be liable to you or anyone else in those circumstances. The supply of products is subject to availability.


The prices for goods and services displayed for sale on this website are as set out on the website. All prices are in pounds (£) sterling, inclusive of VAT. Delivery may be charged in addition, and any such additional charges are clearly displayed under “Shipping Charges”, where they apply.

Prices may change at any time prior to (but not after) acceptance of your order.

In the unlikely event that the price of an item has been incorrectly advertised on this website, we will contact you by e-mail (at the address provided with your order details) or telephone you, to ask whether you wish to proceed with the order at the correct price. If you are not happy to proceed, or we are unable to obtain your instructions, we will cancel the order and provide you with a full refund of any monies debited.

By using a credit/debit card to pay for your order, you confirm that the card being used is yours. All credit/debit card holders are subject to validation checks and authorisation by the card issuer. If the issuer of your card refuses to authorise payment we will not accept your order and we will not be liable for any delay or non-delivery and we are not obliged to inform you of the reason for the refusal. We are not responsible for your card issuer or bank charging you as a result of our processing of your credit/debit card payment in accordance with your order.


Subject to availability, the Twentieth Century Society will use its reasonable endeavours to deliver the goods you have ordered, within 7-14 days of you placing the order, but we cannot accept any liability for late deliveries which are due to circumstances outside of our reasonable control. We will deliver the goods direct to the address you specify when you submit your order.

Deliveries are made Monday to Friday (excluding bank and public holidays), normally between the hours of 8am and 5pm. The precise timing of a delivery cannot be specified.

If your order consists of more than one item, those items may be delivered separately, but we cannot deliver items within the same order to multiple addresses.

Deliveries will be made to your door. The Twentieth Century Society is not responsible for any additional carrying or positioning of goods.

Once delivered, the goods will become your property (provided they have been paid for in full) and your responsibility and the Twentieth Century Society will not accept any liability for their loss, damage or destruction after they have been delivered. Certain deliveries must be signed for.

If the goods you order are not available, for whatever reason, the Twentieth Century Society will inform you of the position by e-mail (at the address provided with your order details) or telephone. If the goods are temporarily out of stock, we will ask if you wish to wait for the goods to become available. Unless you advise us of your wish to do so, the Twentieth Century Society will refund any money debited from your payment card by re-crediting your account. The refund will be made as soon as possible and in any case within 28 days of notifying you of the non-availability of the goods.
