Yes, we have those. At least in the grocery stores I’ve been (Wal*Mart, Target, Publix, WinnDixie, Albertson’s, KashnKarry, Krogers, and Publix) in three different states (Louisiana, Georgia, and Florida) over a seven years’ period.
And like you I go by the second… and choose either the cheapest, or the most adequate for my needs, depending on the case.
