Joe D.24 hours may be too long to give someone -
I guess it depends on the person (do you know the person?) or the item itself....
The number of hours is up to you - but I do think an timed deadline is better than just going to the next person.
Maybe an additional rule that states:
-- All inquiries will be responded to via email. You may lose your spot in line, and the item might be offered to another person - if I do not receive a response back within (X) hours.
