Will the real "Yellow Letter" Please Stand Up?

[William Turner]

Has anybody else had the problem with competing companies with the same name, such as Yellow Letters and Yellow Letters Complete?  I thought there was only one Yellow Letters and that all others would have significantly different names due to registration and copyright infringement laws.  Turns out I am wrong.

I started an inquiry with Yellow Letters and about two weeks later somehow ended up contacting Yellow Letters Complete.  The confusion only came to light after I placed a direct mail campaign with Yellow Letters Complete and then got a call from Yellow Letters asking if I was still interested.
