For those who have been using this - how is the pricing? The reason I ask is that I don't see how Google can make money (especially with free shipping for 6 months) without putting a markup on items. Perhaps they are just trying to gain traction and are willing to bite the bullet for the first 6 months.

I did a quick comparison between a random product: LG 42" Class 1080p 60Hz LED HDTV. Target's direct online store offers the TV for $379, while Google Shopping has it listed for $449.99. I haven't done other comparisons, but this seems to confirm my belief that Google is marking the products up to some extent.
