Effective Saturday, the charge for back issues 1-10 will go up to $5.50. PayPal is taking more of a "ding" out of it than I thought. You can purchase them here: http://www.casefileclues.com/2009/10/back-issues-1-10.html
Back issues of Casefile Clues are grouped in sets of ten. The next set will be 11-20. The price of back issue sets will remain at $5.50.
