Jen, I don't know where you are pricing your epi=pens, but Wal=mart gets 65.00 each.
And yes, family members develop an allergy more than the normal populace or the actual beeks, not only from the equipment, but because as a rule, they are stung more often than the normal person, but less than the beek. The beek normally develops an immunity.
Knowing this, I have never tried to keep from getting stung, as I didn't want to fall into that middle range category.
