Unfortunately, when it comes to MCP, it seems maybe 5 or so issues of the whole run regularly sell for more than $5-7 each, and those are considered "dollar books" here.
I put regularly in bold because I see sales of the other Weapon X issues that make no sense ... one copy selling for $20-30+ right next to a $3 sale in the same condition. Makes me go hmmmm Not just the occasional Divad sale. It does seem a bunch of people are listing the other BWS at sky high prices and hoping, while they're still selling elsewhere for $10 and less.
