I found the last bullet really interesting. At first I thought "wait, UPS isn't a tech company" but when you think about it, any time you buy something on the internet, you're giving money to UPS (or a competitor).
Actually, interesting anecdote... my former roommate once had to ship a load of stuff (100+ lbs) from the US to Canada via DHL. DHL quoted him about $1000 for the whole thing.
Then we went through our employer, who had a deal with DHL... $70 and change.
A friend of mine used to ship things to his office for much the same reason, it was cheaper to ship a large load to a business address (something to do with rates for freight). Once he ordered ten huge CRT monitors, and then sold nine of them to his friends. Ended up both getting a new monitor and making a profit.
