No, but the highest bid was $73, as I said, why didn’t he bid 74, 75, 76, why did he bid just above my supposedly “secret” max of 81? Something fishy.
eBay’s system doesn’t bid in increments for the autobid. So assume you bid $10, max of $30. If someone comes in and bids less than $30, It should have what they bid, then your autobid going higher. But if they type a max bid of $50, it’ll jump straight to the first bid that’s higher than yours, $31.
