People being "fished" by aliens? Ring a bell?

[stevec]

In a small town, a couple of fishermen notice that people keep going missing. They discuss this as they create their fishing flies, talking about how it's the art of the fisherman to fool the fish into thinking the counterfeit flies are real.

One of the fishermen is in a grocery store when he sees the label on a bottle of, I think, ketchup is misspelled. He leaves it and takes the one behind it. The woman next to him doesn't notice the label issue, takes the bottle, and the next day she's vanished.

Clearly, people are being fished by aliens creating counterfeit products, and only those clever enough to notice the subterfuge avoid being caught.

Anyone remember who wrote this story? It must be thirty years since I read it...

smells to high heaven of a Robert Sheckley story

Sheckley - yes, that's quite likely. Care to pin it down to a specific title?
