52 comics at an average price of 3 bucks each = 156.00. A few of the issues are $4.00.
I agree about the ridiculous price (although, IMO the more ludicrous issue is who wants a book full of #1 issues? It's like wanting a meal with 52 dishes out of which you take one bite each and leave the rest...), but there is a mathematical reason why they picked $150.00. It is, by a hair, cheaper than buying all the original issues.
