[Ask] how to properly bump my threads?

let's say I have content that need to be sold...

the price is already ridiculously low, but the thread is already 1 month old and buried deep

I don't have anything new to add,

but I want people to see this thread

how can I bump this thread properly...?

 

There is no "proper" way to bump the thread.

If you want to draw attention to that thread, put a link to it in your signature. (ie: I'm selling stuff. Go here to see: http://forums.digitalpoint.com/showthread.php?t=1131541)
