A one-tab spreadsheet that shows what you really earn on each sale, after fees, postage and costs. Enter your email and we will send it to you, plus the occasional seller tip.

When you press the button your email address is sent to Kit (kit.com), our email provider. You will get an email to confirm your address; the spreadsheet downloads once you do. Nothing is loaded from Kit before that.
