Seems the seller must have put in a wrong initial price. As soon as I had reviewed the email notice I posted the information.
I thought the price was incredible.
In addition to the price now being $169.99 the seller has changed the return policy terms to
"
The seller will not accept returns for this item."

The original ads had a
seven day return for defective items.
Review of pcukid's
feedback page a number of EE's were previously sold in the $249 -$349 range.
Edit:
Thanks all for pointing out the price changes. I have updated the original post.
