Summary: Still highly profitable but the need to be autopricing every minute on the day of prize release heavily outweighs the benefit. The time spent doing this could easily be spent questing instead.
Subsequent days see very few prizes sell, and having lots of prizes massively increases risk of being stuck with unrealizable gains. Managed to recoup MP spent but got stuck with over 400 prizes unsold ( ~200M value)
