Shopping cart cover, yay or nay?

I saw at least five moms with shopping cart covers at Super Target today so decided I should take a look-see on Amazon and I found this Leacho one. It looks really comfy. My question is this: Do you think it is heavy and is it a huge pain to use one? I think it would be useful just for a more comfortable shopping experience, lol, but also the whole germ thing. But then I'd have to wash it every time? What do you say third tri...thanks!
