Wayne R is right on the money as unit pricing is the key to comparing true value. Manufacturers will always be adjusting their packaging and pricing, or some combination. The beauty of unit pricing is the transparency that is maintained through these marketing strategies. I would not waste my time focusing on the virtue of the manufacturers, rather just make wise purchasing decisions. Determine the minimum quality within a product category that meets your needs and then compare the unit pricing for those items that meet those quality criteria. On a similar note, consumers should also periodically re-evaluate the ingredient list when relevant, since manufactures will change them out. Manufactures will change out an ingredient to improve quality, lower retail cost or increase profits. Price is never the only appropriate criteria to look at. Beware of changes in quality. They both figure in overall value, and each consumer must judge for themselves as to the personal value these products represent.
