I have not had any issues with Davidco service, and I have placed my fair share of orders.
It just became obvious to me that I was getting three emails when I was trying to get an article about how to manage email - from a productivity company no less. To me that is a GTD disConnect.
The last time I checked - I don't get three emails from any major online retailer when I place an order. Two at max (one order receipt, and one when it ships).
I will even take it one step further - why have to log in and fill a shopping cart and checkout for a free article? (yes, I know, they are tracking all our activities in their database)...But I think it smacks of inefficiency...
This is not to lay criticism at the GTD/Davidco folks...they are a great group. Again, just an observation.
