If this is about getting the most bang for your buck, turn the page. Wilson doesn't offer that.
Tvad is right, as you seem to know, about buying used. Thankfully, there are still people who buy new so that the rest of us can buy used.
Try another thread asking for cost effective alternatives to Wilson WP-7. You will get a lot of responses and many of them will be valid. I'm going to recommend Zu Definitions because I own and sell them. However, my first bit of advice won't work there because nobody ever sells them used.

Tvad - I think you are probably right and I just did so.This is rather a different situation however. I am not a dealer per se but I do stand to receive a commission if anyone who listens to the speakers in my home buys a pair from the factory. I have no inventory other than my own pair of speakers and no investment to protect. I do not negotiate price and I live in a fairly remote location. All in all, I'm not likely to benefit directly from my comments.
But just as the matter of whether or not Zu uses a crossover evolved into a vast controversy, I fear that this one could as well. So I'll take your advice.
