Ticket prices increase on Black Friday

Hi everyone,

So I was looking to book a flight in April from Korea to Ireland, but was waiting to get paid. Last week the price was €450 for one way, and now, when it’s supposed to be Black Friday, they have put the “original” price to €571 and “lowered” it to €548 ??? Do you think I should wait for the “Black Friday sale” to end before buying a ticket or will it never drop back to €450?

Thanks
