OK here's my luck...
I'm planning kayak or small skiff build in the near future, so I'll need a bunch of these. I have the same clamps and love them, so I was excited to build up my arsenal at $9.99. I checked my Lowes in Wilmington the same day Bas posted and they were $19.95; three days later I was there again, this time I had a price check, same as before. Today I needed a tune up kit for my mower so I strolled by tool section....now the price is $29.95!
The only clamping I'm doing now is on my wallet. Jim
