Re: plywood for hive bodies ?
Before you complain about Mann Lake, you should be aware that they will tell you that shipping foundation in the winter is at your risk. Beeswax becomes very brittle when it's cold, and will shatter like glass at 15F. If you had it shipped when it was cold, you were warned it wouldn't likely make it to you intact. Nothing Mann Lake or anyone else could do about it.
I need a pile of foundation, but will either drive down to Kelley's to get it or wait until the night temps are well above freezing to order it, it will arrive shattered otherwise.
