Roche, Radio Shack, and 2 New 2032 Batteries

When yet another of my accu-chek aviva meters said that the battery was too low, I headed to radio shack. I didn't bring my meter with me. Walking into radio shack, I was greeted by a friendly guy around 50, who asked me what I was looking for. I told him that I wanted a battery, yea big, for my glucometer. He asked if I knew what type of battery, and I said no. He looked on his computer to find the battery type and couldn't. The radio shack computers don't have adobe on them, so that employees won't spend their time looking at more amusing things than customers, so he couldn't open the accu-chek aviva owners' manuel from online. So he called Roche customer service and handed me the phone.
After I picked the correct menu option (I HATE having to pick phone menu options), I was connected with a woman who told me the number of the battery I needed after about 40 seconds, but who then wanted to know all about me. She asked if I wanted a new battery sent to me, and I said sure. I also picked out a battery from Radio Shack, bought that (for 4.99 plus about 50 cents tax).
Well, a few days later there was a fedex box, about 8"x 4"x5" in front of my door. That's a lot bigger than is needed for one tiny battery- ten glucometers could fit in there. On one side of the box was a sticker that was probably the reason for the size of the box. It was red, white, orange, and black. It said:

Attention Fed Ex
Courier/Service Agent Express

DO NOT PUP AS DG

This package MUST be inspected by the origin location Dangerous Goods Specialist

Then there was a picture with a picture of a passenger airplane that said: DANGER DO NOT LOAD IN PASSENGER AIRCRAFT

APPLY LABEL TO SMALL PACKAGES BY WRAPPING AROUND CORNER OF PACKAGE ON DOTTED LINE

PRIMARY LITHIUM BATTERIES- FORBIDDEN FOR TRANSPORT ABOARD PASSENGER AIRCRAFT


My roommate says the sticker would be a cool thing to put on a guitar case. I wonder about how, if the battery in a sealed box can't be taken aboard a passenger airplane, how the hell I would be allowed to fly with it in my pocket? I'm glad I don't fly. I also think that the shipping and handling probably cost more than the battery did and it would have been cheaper to, I dunno, give me credit at radio shack or something like that.

EDIT: Blogger seems to be acting funny. The link to the picture that was in the middle of the sticker is: http://www.mayomedicallaboratories.com/images/specimen-transport/courier/danger_sticker_1.jpg
