Clamps

I know this isn't a good start, but I don't think I own any clamps... I have our Grandad's workbench with a vice, but no clamps.
Was wondering what clamps you guys use and more importantly why, and what for?
I don't really want to ask at the DIY shop because I just know that half the stuff they recommend will sit unused in a tool box for the next 2 years until we build a chicken coop or something
Cheers, Dewi
