Raising a BIN price once you see the interest?

[heartovermind]

Been in this situation before.
We listed a vintage household item.
Based on research of past sold items,
put a BIN price on it. It was under $100.

Had dozens of views + several watchers in a few hours,
several emails by the next morning. Lots of interest.

Turned down a lowball offer, politely citing the interest.

We would like to raise the BIN price by about 10 to 20%
The idea is to deter lowballers.
Is there anything wrong with raising a BIN price

based on interest

once it been seen at the lower BIN price?

That has happened to me and after doing some research, I had priced it too low.  Before anyone purchased it, I just cancelled the listing and will relist it in a couple of weeks.

 I would do as music suggests and end it. Anyone watching it will merely be annoyed the price has risen. Let the Lookie-Lou's think it's gone, and that in itself  is incentive to purchase the next time. 

Also, watchers do not equal buyers.

Your watchers may merely be other sellers with similar items looking to see what yours sells for, or hoping to buy it low and sell it high.

Couldn't they simply raise the price without ending the listing?

Nothing wrong with adjusting prices -- it's your item, after all. Be prepared to get offers that reference the original price. If lowballing persists, consider using auto-decline.
