Lowered Price, Post Deleted

Not sure why me lowering my price on an item for sale was deleted. I reviewed the rules and I was wrong to bump without being a Gold Member, sorry. But I then lowered my price and that was deleted as well. I didn't see anywhere in the posting rules that gave a min I had to adjust my price by. If that is a rule it should be in the "FABO Classified Section Rules" Sticky so EVERYONE knows the rules and not perceived as a mod just deciding it on how they feel in the moment.
