Lend us your word, not your address book.

You can refer once you have an order with us that has been delivered and not returned. You need to be old enough to hold an account with us, and living somewhere we ship to.

A friend is a real person who has not ordered from us before, at their own address, paying with their own card. One reward per friend, however many links they are sent.

Shops, resellers and anyone buying for a business should use the wholesale page instead — the terms there are better for you than this is.

Not at checkout. Not at dispatch. Your reward is earned thirty days after your friend's order is delivered, which is the moment their right to send it back for a refund runs out.

We wait on purpose. A reward paid on an order that later comes back would have to be taken off you again, and nobody enjoys that email.

So: if the order is cancelled, refunded, returned in whole, or never paid for, no reward is earned by either of you. A partial return leaves the reward in place as long as a pen is still with them.

The code is emailed to the address on your own order, usually within a few days of that thirtieth day. It is single use and expires twelve months after we send it.

One discount code per order. A referral code cannot be combined with another code, a sale price, a bundle or a returning-customer offer — the checkout will take the first one entered and refuse the second.

Rewards have no cash value, cannot be exchanged for money or refunded as money, and cannot be sold or transferred. They do not apply to gift cards, and they do not stretch across two orders if you spend less than the value.

Free delivery over $50 is not a discount code, so that still applies as normal.

The programme exists so that one person can tell another person about something. Referring yourself is not that — a second email address, a relative's card, an order to your own flat under a different name — and none of it earns a reward.

Also not allowed: posting your link on coupon and voucher sites, bidding on our name in paid search, buying advertising that points at your link, sending it to people who did not ask, or using our photographs or logo to promote it. The press page sets out what may be used and how.

Where we believe a reward has been earned this way, we can withhold it, cancel a code, or close the account. We will tell you which and why, and you can put your side to [Email] before anything is final.

Indefinitely, until it is not. We can change the reward amounts, the conditions, or close the programme altogether, at any time and without notice.

What we will not do is take back what you have already earned. A reward earned under one set of conditions is honoured under those conditions, and any code already sent to you stays valid until its expiry date, even if the programme has ended in the meantime.

Changes are dated at the top of this page. The version that applies to a referral is the one that was published on the day your friend ordered.

For almost everyone this is a discount on a pen and there is nothing to declare. We do not deduct or report anything on your behalf.

If you are referring at a volume where it starts to look like income, that is between you and the tax authority in [Country], and it is worth asking someone qualified rather than us.

We never ask you for your friend's email address, and there is nothing here to upload a contact list into. You send the link yourself, through whatever you already use.

When they order, they are our customer on the ordinary terms, and their address goes on our mailing list only if they choose it themselves. We do not tell them what you were paid, and we do not tell you what they spent — you will only ever see that a referral has completed.
