I already have, I bought the Amazon module first and then once I saw how much trouble it saved me, I got the

module. Once I start getting orders from Altura, then I am adding that module also.
It has literally saved my sanity to a point. All of my orders are drop shipped, and each order took me an average of 5 minutes to deal with from beginning to end. Now I have cut that down to probrably 1 minute per order.
Also my customer service improved since now I can coordinate each tracking and survey email into 1 application for all of my sales channels.
As far as remote administration goes, while the program is MS Access based, I use LogMeIn.com for free and just remotely connect to my home machine from my full time job. There is a little time delay compared to actually being on that computer, but I find the freedom to be able to process orders remotely so much easier and definitely an option.
