How to 'bump' own sale thread??

[Alexpython]

Might be a silly question but I'm trying to 'bump' my sale thread but every time I write it it goes on the bottom of the original thread instead of a new post? Any help would be appreciated thanks

As mad_at_arms said, wait 72 hours. This is a built in feature to prevent spamming in the for sale section.
