For authors & writers

Sell ebooks and PDFs direct. Keep 100% of the royalty.

Amazon pays you 35% below $2.99. 70% above — minus delivery fees. Linkcase + Shopify lets you sell the same EPUB, PDF, and MOBI directly to your readers, keep ~97% of the price, and own the email list at the end of the checkout.

The problem

KDP owns your readers. You just write for them.

Amazon controls the relationship. You don't get the email. You can't offer a bundle. You can't run a 24-hour launch sale without their approval. And they take 30% on everything above $9.99.

Zero list-building

You never get the reader's email address.

Per-format lock-in

EPUB on Kobo. MOBI on Amazon. PDF nowhere.

30–65% cuts

Depending on price tier and delivery size.

The Linkcase move

Ship the trilogy. Ship all three formats. Keep the reader.

Attach EPUB + PDF + MOBI to one Shopify product. Reader buys, Linkcase delivers all three, and Shopify adds them to your email list. Next launch, you email them directly.
