Many large retailers (wal-mart etc) have HUGE fines to their suppliers for
non-scannable barcodes, for whatever reason.

The laser scanner readers are often impaired by "gunk" on the optics,
because they aren't properly maintained. This adds to whatever challenges
are imposed by bad printing, plastic over-wrapping, condensation, frost, etc.
