According to the Consumer Contracts Regulations, which implement the Consumer Rights Directive in UK customers have 14 working days (beginning the day after receipt) to cancel a purchase.
Order cancellations must be made in writing to Customer Services at firstname.lastname@example.org quoting your order number.
If you cancel an order you must return any cancelled items to us within 14 days of your cancellation. We will provide - within 14 days of receipt of your notice or, if applicable 14 days of receipt of cancelled items if this is later - a full refund for the unused items returned in their original, undamaged packaging.
If we don’t receive the cancelled items back, we may arrange to collect them from you, but sadly this will be at your cost. For full details click here.
