In the US we currently have low inflation and this is not expected to last. Inflation will increase in the years ahead. If we compare what happened from 1977-82 to the present and near future, this is what would happen:
2010 ... $7.99 book will cost $12.72 in 2015 (almost $1.00/yr increase)
$14.98 in 2020
$21.16 in 2030
$27.34 in 2040
