I have just been down to Lidl and they have one handed style clamps on offer at 2 for £1.99 which for the restorers among you is a pretty good deal. They also have G-type clamps but they do not look great.

The weenie ones are useful for stopping your jib un rolling in the bag.

Another top tip from Dan.

B and Q had little ones for 99p each at the check outs

This person seems to have enough clamps...

you can never have too many clamps

Not only has he got a lot of cramps, he's got Bessey cramps! Loadsa money ;-)
