That's a big reason store brands can be sold at a lower price -- they have a
lower cost for the identical product because they're not burdened with the
advertising costs of the national brand.

Contraiwise, they may also have lower tolerance components, or the same
components, but fall in a quality-control-acceptance zone lower than the
other product produced in the same factory. This has been somewhat
documented with tiawanese/chinese woodworking tools, where you might
think the only difference between 4 brands of "apparently identical but
for the paint color" tools are produced from the same castings. One
paint color gets better castings, different bearings, etc...
