Since I placed one order via this unscrupulous reseller of cheap crap, I have received countless catalogs from other such peddlers such as:
Harriett Carter
Starcrest of California
Worldwide Herbals
Heartland of America.
A Starcrest representative confirmed that my info was obtained from Dr Leonard's. After a quick Google search I found they use a company called "Exact Data" out of Chicago to sell YOUR name and address to others. I contacted them and was given several quotes for lists.
I have had to call each one of these "catalogs" to get my name and address removed from their mailing lists. Unless you want to receive unwanted catalogs of cheap, crappy items stay away from this company. Your name is worth more to them than the profit from any order you place.
