do you want contact info everywhere 

do you want contact info everywhere

NO - unless you really want the loads of calls or you are just lonely, don't do it. It's all very well to say that you may make a lot more sales, but the flipside to this approach doesn't become apparent until you have lots of sites selling lots of stuff and can't get to the toilet because you are stuck on the phone.
You could always say that you'll just employ people, but then you have them to deal with as well as the constantly ringing phone.

I accept the above points about high ticket items, but thought it was worth posting a balancing comment.

Imagine if every visitor you had called u every day - if you can deal with that, go for it.
