Went to Bunnies looking for mini kwik-clamps. Duh, what are they?
Sent SWMBO to do a lap of the hardware stores, most used to have them but don't now.
Edgeworth David Hardware (Thrifty-link) told her they'd see if they could get them. Before she was home, they rang to say they'd have them by next Wednesday.
A simple thing, but they'll get the business.
