Looks to me like zero relevant hits. But I must be on a list somewhere...
When my hearing deteriorated I started getting hearing aid ads. I accused Mrs. JimRed of putting me on a list; she denies it. I don't recall ever searching hearing aids online. Now I have them and I get 2-3 mailings a week from other HA companies, along with the online ones.
And there's a whole raft of lovely young Russian and Ukrainian gals who wanna meet me, too!
