(Employment) Well, what can brown do for me?

I returned home from college this Friday in anticipation of working at The UPS Store on Saturday to find that UPS Corporate had sent me a little postcard in the mail informing me of their job opening for Seasonal Driver Helpers. Little details other than the promise of $8.50/hr were included. So, out of benign curiosity, I decided to google said position. Namely a search for UPS Seasonal Driver Helpers and oddly enough I can't seem to find the exact position I was offered in the first place on job listings. One offers $8.00/hr for Seasonal Delivery Driver Helpers, another (in Louisville, Kentucky) offers $11.75/hr for a job with the exact same name and description as well as $8.50/hr for a job with UPS Worldwide sorting package from ~11:30 PM to 3:00 or 4:00 AM. All of this news notwithstanding, since I'm certain it's mostly price fluctuations based on locality and need therein I begin to wonder what prompted UPS to send me such a note (and how they found me in the first place) because with all the facts considered, they're practically offering me a job in lieu of a job with a subsidiary of themselves, and that doesn't really seem like the most brillant of plans. Either way, riding around in a truck for 12 hours a day with a man who's most likely a smoker (and has all the more reason now that he's got someone else to do the walking) is not my idea of a Seasonal Job, especially because I don't think I'd even get a chair.
