For example, my amps sold about 2-8 per week, some week none and next week I had to resuply every other day, so 1 week is bit too quick for conclusions.
So no problem to re-new once again your offer in case its not selling well this week. You should care about your business, not to flood markets once in 4 weeks and than do nothing idle.
Maybe if your offer loose 50% of prize for every started week over first 7 days. If no one wants it for a long time, I would bed the merchant will lower the prize to get rid of it and make space for better items... Or something else. But I can't vote for any feature that only makes life easier and brings no consequences or effort.
