One thing to consider, aside from where a product is made, is the materials used to produce it. Same manufacturer, plant, line or molds but utilizing different base ingredients produces a similar product but not the 'same' product. A name brand would never allow an exact match as it would negatively impact their own bottom line and undercut the brand itself.
For the consumer it comes down to intended application and effect, sometimes cheaper is 'good enough' and sometimes it isn't. Deciding which is right on any given occasion is what keeps the Bait Monkey on it's toes!
