H&R Block is taking a cue from AOL. In major computer magazines this month, H&R Block is providing free CD-ROMs of its TaxCut tax software to readers. The CDs were spotted in PC Magazine and PC World. The same program costs $10 on TaxCut's Web site, so it's a pretty good deal. It's the federal version only, so H&R Block still can make money from you when you buy a state version (if your state has an income tax, that is). You just peel the plastic coating off and insert the CD into your Windows computers and it begins installing.
