[support] Ecommerce Free Text Input "Attribute"

[Fred Jones]

I am certain that this question has been asked before, but I can't find 
the answer. I am just now starting a new estore and we need to allow 
open text inputs for products, so users can send us their name to be 
monogrammed, for example.

I don't see a way to do this with ecommerce. I would be willing to 
switch to ubercart if it has this, but last time I looked it I don't 
recall seeing it.

Is this doable with either?

Thanks.
