A number of stories today about shopping comparison engines…

Mylene Mangalindan writes a piece in the WSJ Personal Journal section. The article mentions Smarter.com’s coupons, Vendio’s toolbar, and BuySafe’s antifraud guarantees as services offered by “a new crop of start-ups [that are] pushing the price-comparison concept even further.”

SNAP.com announced the luanch of it’s shopping section powered by Smarter.com. Nice to see the little guy land one of these deals.

Finally, Shopping.com is the first to the table to release a Holiday Season story. Expect a flury of these in the coming weeks.
