Pay the $1200 before someone else offers $1400 for it. Why would you even try to get the seller down from a $1200 asking price for a fairly nice Haunted House?
And people wonder why pins get bought out from under them!
Why - when something is being offered at a "fair price" does everyone feel they still need to pay less. 25 to 40% of the time when I buy pins I end up paying over asking price to be fair with sellers.
