Almost caught myself slipping --
1) Some guy offered a lowball $30 offer and then a higher $50 offer (2 seconds later)
2) Grailed has a major flaw in that it only registers the lowball offer if the higher offer immediately follows
Was gonna accept the $50 offer, but noticed that the Accept Offer # was still $30 lowball offer (even though the most recent offer was $50).
Very slick and surprised Grailed hasn't fixed this. Stay safe out here and carefully make sure that the offer amount is correct before you Accept Offer.
