Refunds

Returning unwanted goods
7 days to cancel purchase for non-faulty goods

In the EU, you have the right to cancel your on-line purchase within seven working days.

This seven-day “cooling off” period begins on the day when you receive your purchase.

You can choose to cancel your order for any reason within this time frame – even if you simply changed your mind.

We will give you a refund within 30 days. This refund must include any shipping charges you paid when you made your purchase.

Although you have a right of refund, you will have to pay the postage costs of shipping goods bought on-line back to us.

Worldwide returns:

Our voluntary returns guarantee: You may return, for a full refund, any item ordered from us within 30 days of receipt, provided it is in perfect condition.

Please contact us to obtain a returns authorisation by completing and returning this cancellation form, emailing (books@psychobabel.co.uk) or telephoning +44(0)1235 861411. You will be responsible for the cost of returning the item to us, unless we delivered it to you in error or it is faulty. It is your responsibility to ensure safe return of the item.

If you return a high-value item, we recommend you use a recorded delivery service. Once we've received your item, we'll refund the same means of payment as you used to make your purchase. This returns guarantee doesn't affect your statutory rights and therefore doesn't affect your right of cancellation described above.
Emails are usually answered within 24 hours, except at weekends.
