I guess we just need to define the metro, I was considering it pretty much the entire city area until you start hitting pure desert.

i.e. the end of buckeye out west, edge of apache juntion and queen creek, etc.
I don't really think a 30 min drive for example is a big deal, we have nice roads here for sure. I have a friend that lives out in buckeye, on the west side of it off watson I think the street it, and its a 45 min drive for me from the 101 and 202 intersection of tempe. Dead middle of the metro valley basically, it would suck to go to his house if I still lived out in east mesa at crimson and baseline.
Everything is of couse going to be situational but I totally agree being asked to deliver something that is free or insanely cheap is a bit silly, with exceptions like medical stuff or what not. I think though it's not bad to try to work something out thats still fair. Similar to what we did when I picked up those frags. You were already going to be in the area for work, so I worked around your schedule and didn't have to burn gas, and you would have been there either way, whether I purchased stuff or not, so you technically made money on the companies gas dollar so to speak. Even still to me it was a big deal to not have to drive way up where you live and I had that extra 10 above the 40 I planned to spend, and you brought xtra freebies, so I sort of saw it as a thanks both ways kind of deal. I don't think it would be a bad thing to ask someone for a bit extra if you are having to go out of your way for them.
You can only compare to a retail scenario so much also. Being the store has stock, tons of other stuff, etc you have to beat out their total 'value' to the customer. Sometimes I see frags for sale in here and my eyes widen in shock at the insane cost, but usually frags are much cheaper here then I would find in a store and a bit more unique which is cool, but if its not a big enough of a value difference people are not as inclined to go the distance.
Man, I sort of typed a novel...
Phx metro isnt bad to drive AT ALL (IMO)... its the far out locations that seem kinda tough to make it to... To me, if your(seller) location is near a major freeway, then getting there isnt an issue at all(unless its rush hour)....
Think about it... How far do you drive to go to the LFS? sure some of you live really close to these stores, but what about those who live in Chandler, Gilbert, Mesa, Etc and still visit Aquatouch... If people will drive 45minutes for a retail price, why wont they do it for private sellers?
