Do you have your domains for sale at Sedo? Did the bidder at Sedo cancelled negotiations before you had a chance to present your lowest price? Do you want to contact the bidder but you can't? (Does this sound like an infomercial or what?)
Well after Sedo introduced this feature you can:
"Set your domains at a fixed Buy Now price and all previous bidders will be notified about the new price and can purchase the domain name instantly!"
So you just set a price and the bidder that canceled negotiations, along with any previous bidders, will get your new lowest price. Sedo will send them an email informing them that your domain name is for sale at a "Buy Now" price.
After setting the price at the Sedo control panel be sure to change the "Price Option" from "make offer" to "Buy Now". If you don't then the bidder will not be notified and also in case of a sale, the Sedo sales fee will still be 15% instead of 10% that is if the domain name is also parked with Sedo. (These fees apply to sales that are NOT originating on the SedoMLS® Promotion Network)
