We tried this, and received emails from customers who saw one price in SERPs, and another price online. The customers either felt a sense of mis-trust that they were not getting your best-price on all items, or they would simply demand the lower price for that specific Widget. As long as you rarely change the Widget price, it would be less of a problem.

But be prepared to honor the lower price when you have price-adjustments. Outdated SERPs can stay around a long time.
