I sold a TZ at a low start for pretty much exactly what I would have expected at the time, and a DE Star Wars for once again what I expected. In both cases though I had to hold my nerve because things really didn't happen until the last day and last hour etc. But its a risk if that action doesn't happen. Pity Epay doesn't allow reserves here like most other auction processes.
If I was firmly fixed to or needed a minimum price, then sure, the buy it now / make an offer etc can be worthwhile, and are a good option.
