Whole Foods already carries all that stuff.
The thing I hate is they don’t carry regular Aspirin or Tylenol, Nyquil (your usual and basic over the counter medicines) instead they carry ‘homeopathic’ whatever useless ‘natural’ ‘medicines’ & ‘supplements’
Amazon has a big opportunity there as well. They've just started their vitamin Solimo brand which is actually decent, and private-labelling generic drugs is just easy money for most retailers.
