In general, I will never purchase anything on those terms. I find it ridiculous and it insults me as a customer. When I see those auction, I automatically skip them.
If one wishes to sell an item for no less than $200, then state the price honestly and let the market tell you if you are in the correct range.
I find many sellers on ebay can't be arsed to do any real research on the real market value of an item and that bothers me. Any time I have sold there, I do my research, set my initial price slightly below what I would find fair, and let the buyers decide. When something is too expensive, people simply won't buy it. Where is the benefit for either party in that?
