Here’s a page of eBay ads for the special edition newspaper with wrap. Seems like some are selling just the wrap alone. Others, the entire paper for roughly 3x the amount, thus the $7-20 asking prices.

There are 775 NY Post Supreme for sale on ebay.
There’s only two that have sold so far. One at $9.28 and the other at $5.75.
Supply far exceeds demand.
