Went into my local LV today. Saw the display for the Bessey Bar Clamp sets. Then sitting on the table beside the clamps was a display model for the Bessey 90 degree corner clamp. That's a beefy heavy corner clamp.
$15 CDN I thought it was a good price and grabbed it.
Later I checked; LV does not sell this item online. Rockler and Woodcraft have it advertised at $29 USD.
If you interested, and live near an LV and looking for a corner clamp, it's worth driving over and taking a look.
