soundforge pro 13 is €399, soundforge pro 13 suite is… €599… to say it in euro’s…
spectralayers full version in €… is €299 from steinberg.
if you have soundforge pro 12, you can upgrade for €249, i checked. i was curious. have soundforge pro 12, for a few a dollars… (humble bundle…).
so you compared it, as Mobius already guessed, with the wrong version or better: bundle. the suite is a bundle with now outdated ozone 8 elements, etc.
