The present way we do it is if a customer support peeps gets a ticket about an order they inform someone who passes it along down the chain.
Really? You might want to audit how your current system works. Here's what happened yesterday:
Me: Hey, can you add something for me to the order I just placed (100079256)
Vision Vivi Nova mini
all heads at 2.4
Ethan: Hey there Jeff, unfortunately once an order has been placed we have no way of editing it or else I would for you

-ethan
Me: Ethan, can you delete the order so I can reorder?
I received no response, and my order shipped the next day (today). Guess I have to pay another $15 in shipping. But the question is, with who?
Funny thing is, Ethan *did* edit an order for me in October for a similar thing: October 1st, 2012: "Hi there Jeff, I got to your order in time. I swapped that stuff out for a T2, and am refunding you the difference! -ethan". So Ethan did help me out with the same thing in the past.
Now I do realize that this is all really my fault. I should have shopped more before hitting the order button. But the difference between one vendor and another, a lot of the time, is the convenience at which one does business.
