Graco Snugride infant car seats?

I've been looking online for an infant car seat, and I would really like to get a Graco Snugride car seat. I chose one on Albeebaby.com., that is 127 dollars before shipping and tax. Last night at walmart, we decided to look at the car seats, and they had a Graco Snugride winnie the pooh design. It was 89 dollars before tax. The problem is, the material was so thin, you could see the plastic part of the car seat through it, and I stuck my hand underneath the material, and there was nothing, no padding or anything. It was like a sheet laid over plastic. Doesn't seem to comfortable to me. But on Albee baby, the Milan style Graco Snugride says that it comes with energy absorbing foam, and gracopedic foam for Luxurious comfort. What do you think? Does it have more underneath than the model at walmart, or are they just saying that. The car seat at walmart had literally nothing underneath it, and had 2 styrafoam pads next to where the head rests, and the rest of the car seat was plastic. I don't want to pay 127 dollars online, if its going to be as cheap as the one at walmart. Anyone have the carseat from walmart, or another graco snugride, that you can tell me what's underneath the car seat cover? Thanks for your help.
