a- I bought this off my neighbour.
b- I bought this off of my neighbour.
c- I bought this from my neighbour.

Are they all correct?

 

[emsr2d2]

BrE frequently uses "off" there, as well as "from". Please don't use "off of". It's a really annoying habit that some native speakers have and it drives many of us insane!

 

[probus]

Notwithstanding emsr2d2's understandable aversion, a descriptivist would accept "off of" as valid because it is used (at least in AmE) and has been for a long time. If I heard it, however, I'd assume the speaker was uneducated.

 

[Skrej]

"Off of" is commonly used in my area, to the point it might even be the preferred form. I can't say for sure, but it is widely used and extremely common. I use it as well.

But then maybe we're all just uneducated.
