I use it to find retro brand stuff or close copies. Many of the discussion groups offer up valuable feedback on stuff. My true coffee and tea drinking favorite, the Sunshine Golden Raisin Biscuits had been off the market for 20 years. Product feedback forums helped me find almost exact versions. I then discovered there were thousands of people looking for the same “Gone” products which are still made in unknown places under unknown brands.
Exactly.
I have done the same.
