We have an Extended Christmas Returns Policy for 2020 that requires that most orders shipped between 1st November and 31st December (inclusive) be returnable until 31st January, 2021.

Outside of the above policy we offer a no-quibble 30 days return policy. If you no longer want it, for any reason, you can return it to us. If 30 days have gone by since your purchase, unfortunately we can’t offer you a refund or exchange.

For the full returns policy please click here.

2020 has been quite the year, and the absolute worst way to end would be to order too late for us to deliver in time for Christmas.

Coronavirus has played havoc with delivery schedules this year, however, we have it on good authority from Royal Mail (our main shipping provider) that as long as you order before 2pm on Friday 18th December your order should reach you in time for Christmas.

Note: this is for UK mainland addresses only. If you live abroad then you need to order some time before this date in order to have your items arrive. Due to the nature of international deliveries and the vast number of countries, we are unable to provide any guarantees that your order will reach you in time for Christmas, sorry.
