BTW - we're all assuming it's cost-cutting (and it probably is). But did anyone think that the reason they went to this was to at least keep some soap? For all we know the soap companies may be raising the rates so that the only way they can keep something decent is to do the hollow bar. Granted an extreme example.
But back to my thought - hollow soap I can deal w/. I'd rather complain about important stuff. To me (personally) soap ain't it. OVMV.
Cheers.
