I dont think so either. Im not saying it would cause any deep issues, but there will certainly be at least a few people out there deterred, albeit illogically. For a reactionary leaning the wrong way before they even type in myec.com, it becomes "what a lame website. Their offer is probably too good to be true", or some other stupid justification for allowing themselves to react "no" in a "path of least resistance" move.
The smart move is to nail every aspect of customer interaction, and the internet has become more valuable than a phone book in its heydey imo.
