Slightly lower brands of alcohol...
One thing that strikes you in the alcohol world is that oftentimes a manufacturer will put out a brand of rum/whiskey/vodka that looks similar to the "premium" brand, at least at first glance, but is not the same as the desired brand. This knock-off is not usually of the same caliber as the high level item, but I suspect that if a person was drunk and in a hurry for more booze, the lower price, as well as the "just as good" looking label, would be sufficient for purchase.
Here are a few examples of the Premium, Knock-Off, and "Economy" versions (or at least envisioned by The South of Iowa).
Premium: Captain Morgan
Knock-Off: Admiral Nelson
Economy: Deckmate Dickey
Premium: Jack Daniels
Knock-Off: Evan Williams
Economy: John Doe
Premium: Southern Comfort
Knock-Off: Midwestern Displeasure
Economy: Northern Constipation
