Changes on the LBM scene across the country in March have been as raucous as the weather. Among the announcements:

¦ Marjam Supply bought Lainhart & Potter, the 119-year-old hardware and supply store that’s the oldest business in Palm Beach County, Fla. Lainhart & Potter filed for Chapter 11 bankruptcy this year and was set to be auctioned off on April 5. Marjam plans to keep Lainhart & Potter’s two stores, in West Palm Beach and Jupiter, but relabel them with the Marjam name.
