To quote another member on the forum:
"To those people who have Lone Wolf books 21 and above, these books
are worth a LOT of money on eBay. Especially books 22, 26, 27 and
28. Each book can fetch in excess of US$70 easily.
So if you want to sell them, make sure you're not getting ripped
off."
To those thinking of selling to this guy, don't be foolish. You are
being ROBBED!
