Taking into consideration how this site commonly uses the word, lowball, it is widely known that the majority of the CAG community associate it with a kind of auction. Having said this, you are using this word out of context, and I don't think you know what the word means:
"The Low-ball is a persuasion and selling technique that works by first gaining commitment to an idea or item at a lower cost than you actually intend to charge, then, using the fact that people will behave consistently with their earlier commitments you raise the price."
See, this does not fit in w/your auction type. You might wanna look into changing your thread title. That is if you aren't misleading people intentionally to get views.
