There are over 50 of them all fresh and new for the year in the cabinet along with oils, flours, sugars, some pasta and sauce, etc etc.People love that stuff and those kinds of simple things can set you apart.

If anything I would say BH is an insurance company, but they do obviously have the real estate piece, oil and gas, apple, some big Japanese compioes, building suppliers like ACME brick, BNSF railroad, and I'm sure a lot of other pieces and parts.   

Our oil company suddenly wouldn't service if they don't deliver so we had to find a new 24 hour service.

You might be able to shave off about 1 point or so.

Or are there courses that aren't snake oil?

., and the things I'd keep is strictly the oil, ags, infra assets and REI.  

Buy a lot of these if you renovate plastered houses.Learn how to use a block plane to shave down wooden doors.Don't ignore hearing and respiratory PPE.
