Clamps in England

Hello,

Where can I buy clamps to clamp with in England? Can any of you UK people tell me which shops I should hit?
Thanks guys

B & Q.

Im in canada. Is there a way to find a medium and large clamp that will not cost like 30-40$ can. Because if I order from cableclamp, I need to order a pack which is imo costly since I will use only 2 of the 15 clamp. If I order from a us shop, shipping cost kind of a lot for a 100grams package, which will turn out to be around 20-25$ can.

And I try searching it on wal mart and can’t find any.

ideas ?
