Infrequent blood donor here. Universal donor O-.
Just been offered money to donate my blood. Very unusual and very strange. Normally just a reminder and a cookie. Received notice asking me to donate along with a raffle for $10,000 from local blood bank.
Been recently receiving more reminders about blood donation.
It might be because O- is one of the more rare blood types (6.6%). I remember a few years back they were also offering money to those with B- (the second most rare).
O- here as well. It not just because we’re rare but universal donors.
