Delivery is instant and automatic, so once you've received your file, refunds aren't available.

If something's genuinely wrong on my end, though, I'll always fix it. Send over a file that's damaged, missing, or printing incorrectly, and I'll have a working copy to you quickly, at no cost.

There's normally no window to cancel an order after checkout, since delivery happens the moment you complete your purchase. EU/EEA buyers: the FAQ page explains your 14-day right to cancel and what completing checkout means for it.
