I just went back and looked, this is the one I bought. Only 9 bucks! It's pretty serviceable, you just have to make sure to pull it all the way over the top or like the last inch or so up there will get wet (though not if you combine it with an umbrella).
As a long time backpacker, I can tell you that this advice isn't that great. Pick up a cheap one of these instead. Grocery store plastic bags are rarely waterproof. If you insist on using plastic bags because you don't want to spend $8 for a waterproof rain cover, then use the black/thicker plastic bags you get from the liquor store. These are much less likely to have holes and won't tear open when you desperately try to stretch it over a backpack.
Edit: I was referring to stretching it over a day-pack sized backpack. Obviously if you have a larger backpack, you're not going to try to put a small bag over it. If you have a big bag, use a sturdy trashbag like those force-flex ones. Or yano, get the rain cover linked above.
