Oh man, c'mon... take the crappy late night info-mercial products back to where they belong - Walmart!
You're an adult right? Ok good, now that you're all grown up, time to put some real winter tires on your car before you kill yourself or someone's kid. At the first site I checked out - discount tire, I clicked on the first set of quality winters I found + some steelies - total all-in = $700 + free shipping. Any local tire shop (non-stealership) will have similar deals.
Now that you've got those winters on there, time to also create yourself a little "get unstuck or gunna be stuck for awhile" kit... because as we all know, winters or no winters, s*** happens. In the winter you should always have some kind of chains with you, but it's also worthwhile to have the following: Small folding shovel, small bag of kitty litter (non-clumping), extra pair of gloves, flashlight + batteries, couple candles + lighter, couple space blankets, couple cans of beans + can opener. There are many more things you can and probably should add (flares, first aid kit, tools, etc) but if you pack this stuff right it will all fit into the back cubbies and spare wheel well... so there's no reason not to have this stuff.
(and ps. just so you know, AWD/4WD doesn't help a car stop in snowy/icy weather... they need winters just as much as a two wheel drive car)
