Plus $6.85 shipping!! I can buy this same battery at Walgreen's
Drug Store for $9.99.

Plus tax, plus wear-and-tear on your car, plus your time, plus the
cost to repair the parking lot incurred door-ding caused by little
Jimmy getting out of his parent's Lexus.

$11.85 delivered to your door seems like a bargain in comparison.

Not if you're already going to the store or need other items from the
same place, which most people do on a regular basis.

Personally I'd rather get off my ass, get out and have a little human
interaction once in a while than pay more for postage than the item
costs. If a substantial savings of time or money can be realized by
ordering online I will and often do, but for something like a
battery it's easier to just go to the store.

You somewhat contradict yourself here. At first you state that you'd
go to the store when you need other items, too. But you end by saying
that just for a battery, it's easier to go to the store. That makes
it sound as if you decided you needed the battery, and jumped in the
car to go get it.

If it's something I need *now*, I'll pay for the gas, pay for the car
wear, pay the 8% sales tax, and get the item *now*. If it's something
I don't need immediately, I'll let UPS deal with the traffic (I live
in Southern California.) My time is more important to me.

As for "human interaction", I can think of countless better ways than
grabbing a battery at Walgreens.
