Collect Pre-orders

What you'll get

A short method page from Learning Loop for testing demand with money: put up a product page or crowdfunding campaign that takes pre-orders before anything is built, tell buyers plainly that they will be refunded if too few order, and let the pace of orders decide when to start production and how big the first run should be. The publisher sells a printed card deck though the page itself is free, and it says nothing about the legal or tax side of taking money early, so check those before you open a payment page.
