There are lots of other shops out there that do what I do, I don't want to limit their advertisement strength or competing against other well known shops that don't even need advertisement.

I would disagree that longer messages is better though. I prefer to keep /tr on, but when someone's ads take up many lines of space, I turn it off, because it's just too annoying. Being concise in your words makes an advertisement more appealing.
