Thats not all either. You probably didn't notice when the industrial standard of a 4.5 by 4.5 inch sheet was reduced to a 4.5 by 4 inch sheet. No announcement, no notice, it was all about adding to the bottom line. Now it looks like the 4.5 width is being trimmed to get a 4 by 4 inch sheet.
These small changes in reducing the amount of product the consumer actually gets equals millions to the bottom line.
