You did the Make Em Beg thing properly. Asked the questions, held the pitch, and got a group of people practically asking when they can buy.
Then the owner opens the cart. The link goes out to their list, their socials and a dozen other places. The launch thread fills up with "just grabbed it!" comments, and you recognize half the names from your DMs. Your people bought. Just not through anything that says they were yours.
The owner isn't trying to shortchange you. They honestly can't tell. So you spend a Sunday night scrolling back through months of DMs, screenshotting conversations to make a case for people you know you warmed up. Then they offer to "call it roughly half," and you take it, because arguing feels worse than the money.
Preselling makes this sneakier. The more patiently you warm someone up, the longer the gap before they buy, and the easier it is to lose track of who warmed them.
Compare that with the cart opening and every one of your people buying through a link that's yours, each name landing on a list with yours beside it while you sleep. No screenshots. No case to make.
Has a presale of yours ever ended in a "let's just call it roughly" conversation?
