I am looking for a cheap single shot 20 gauge, 12 would work too.

Try Walmart or any place that sells guns.

Thanks hadnt thought about the most obvious solution.

I am looking for a single shot that someone wants to get rid of cheap.

Wally world is probably wanting to get rid of some for around $90-100 I would imagine. Whats a used one worth? $60???

For that much most people would probably just hang on to them.

I got one from K-mart a few years back for $75.
