Americana but OK
on 29 December 2009
Bought this based on the good reviews that it had from previous reviewers. As a reference source it's OK but it's certainly not advanced and as most Americans do it doesn't think outside the American borders. I'd still recommend buying it if you need a clear framework for your sales technique but be aware that it's as in depth as it could be.
