This won't take off... The old-guard retailers in the industry have had it up to their noses with bul$%$^% "consumer safety seals..." on top of being scared wide-eyed of Google stepping into their business... Leave this seal to the no-name-just-getting-started retail shops who have nothing better to do with the real estate that the seal takes up on their page. In fact it'll just make Google look like tricycle wheels of the web for babies. Savvy online consumers have enough confidence in the review sites and their credit card company policies to care about Google trust symbols. And businesses with any funding/branding etc don't need/want it.
