I took a look at their website. The "About Us" link may provide some clues.
It sounds like they started in the 1950s. My guess they are pretty old at this point. Notice this comment:
"We lived modestly and I was able to serve in the full-time unpaid volunteer ministry (known as Pioneer Ministry) for 30 years until health and nerve problems prevented continuing."

I wish the couple well. I have purchased from them over the years.Like most old-timers, my guess is that did not plan on being in this old system at this point in their lives.
