Last week I got an inquiry for my only LLinc.com domain that was listed at $650 just to liquidate. We agreed to move forward but the buyer disappeared for few days (now he's back). I was kinda pissed and I removed the price altogether.
As a part of my pricing strategy (and research), I always look up the GoDaddy appraisal tool. So the appraised value for my LLinc.com domain was $4,185 last Friday. Today I refreshed the page (to ensure my price is no longer pulled from Afternic) and it's now showing $3,762.
It seems GoDaddy's valuation is constantly changing.
