Merchandise and special editions
Sooner or later someone suggests you sell more than the book. A tote bag with the cover on it. Mugs. A T-shirt. A signed edition. A boxed set of the trilogy with a map in the back.
Some of those make money and some fill a cupboard. The difference is not taste and it is not effort — it is one rule, and with it you can sort any suggestion in about ten seconds.
The rule
Readers buy more of the book. They do not buy your brand.
Someone who finished your novel at two in the morning and immediately wanted more of it is your buyer. What they want is another hour inside that book: a better copy, a copy with something extra in it, a copy signed, the next one, the map of the place. That is a real appetite and it is easy to satisfy.
A tote bag is not more of the book. It is a bag that advertises you to strangers, and it sells only to people who already want to do that — a genuine audience, and a much smaller one than you think.
What tends to work
A signed copy. The reliable one. It costs you the book, a pen and the postage, and it is the single most requested thing authors are asked for.
A hardcover of a book that exists in paperback. Same text, better object, an obvious reason for an existing reader to buy a second copy — as a gift, or for the shelf. A dust jacket edition does the same job again.
A bundle of a series. Three books together, one shipment, one decision. People who liked the first one will take the set, and it is a clean way to move stock you already hold. See Box sets and omnibus editions.
A bookplate or a signed sticker. A signed, dated adhesive plate the reader sticks inside their own copy. It weighs nothing, posts anywhere in a plain envelope, and turns a book bought from a retailer into a signed book without either of you shipping a book.
Something that is already in the book. The map. An illustration. A recipe card. A character portrait. These work because they are not merchandise at all; they are a piece of the thing the reader already loved, printed larger.
What tends not to
Apparel, mugs, totes, keyrings and phone cases share a shape of problem:
The margin is thin. Once the blank item, the printing and the shipping are paid for, what is left per unit is small, and the small number is the same whether you sell six or six hundred.
Apparel has sizes. Five sizes multiply every decision, and you will be wrong about which ones. The unsold sizes are the ones you ordered most of.
The audience has to be large first. Branded goods sell in proportion to how many people want to be seen as fans. That number is a function of fame, not of book quality, and it arrives — if it arrives — long after the book does.
None of this means never. It means treat it as a thing you do once there is visible demand, rather than a thing you do to create demand.
Special editions are the strongest version of this
A special edition is the one piece of merchandise that is entirely made of book. Sprayed or stenciled edges. A different cover for the same text. Foil or embossing on a case. An extra story, a deleted chapter, an author's note, a map, in the back matter. A signed and numbered run.
These work because they are exactly what the rule predicts: more of the book, sold to people who already finished it. They also reuse production you have already done: the text is set, the design exists, and what changes is the object.
Two practical notes. Not every finish is available from every printer, so decide where the edition is printed before you design it, and check that printer's own current specification rather than a figure from a blog. And a hardcover is not a paperback with a stiffer cover: the spine is different — at Amazon KDP the hardcover spine is the paperback bulk plus 4.8 mm (0.188976 in) — and KDP's hardcover runs 75 to 550 pages, against 24 to 828 for paperback, so a very short book cannot have one there at all. Paperback, hardcover, dust jacket: what changes covers the geometry.
In the Cover Maker. One design produces up to eleven wrap files across perfect bound, case laminate and dust jacket, each cut to that printer's own geometry with the spine computed from your real page count — so a hardcover or jacketed edition is a re-export rather than a redesign, and Mockups shows the object before you commit to a print run.

The part nobody plans for
Every direct sale means you are now a very small warehouse.
You hold the stock. Copies arrive in boxes and live somewhere dry and flat. Books bend, corners bump, and a bumped corner is a refund.
You pack and post. Each order is a padded mailer, a printed label, a trip. Twenty orders is a pleasant Saturday. Two hundred is a second job, and it arrives in a week you did not choose.
Postage decides the margin. Domestic post on a single paperback is manageable. International post on the same book is often a large fraction of the book's own price, and the customs paperwork and any duties vary by country and destination — check both before you quote a flat worldwide shipping price, because absorbing the difference silently is how a sold-out run loses money.
This is the argument for bookplates, and for selling the signed copies at events where you are already standing next to the stock. See Selling books directly to readers and Events, signings and selling books in person.
Signed copies, mechanically
Get stock the cheapest way available to you — print services generally offer authors their own copies at a reduced rate, so check what yours charges. Order more than the orders you have; damaged copies happen. Sign in batches, in one sitting, with the books fanned so the title page is exposed. Events, signings and selling books in person covers the pen and where on the page to sign.
Then decide honestly whether you want to do that fifty times. If the answer is no, sell bookplates instead. That is what they are for.
Make yours
Everything here is built into the tools, and they are free to use: name your book, bring your manuscript or your artwork, and work as long as you like. You only pay when you want the files without the preview watermark.
