Costco's Pesach Ad in the AJN

The most recent issue of AJN has a full-page ad from Costco Wholesale urging us to "stack up the savings for Pesach" by shopping with them. The impression of the accompanying picture is that it is tempting us with an assortment of Costco's Pesach items.
While this may not been the aim of the ad, it would have made sense to advise Costco that Vegemite and peanut butter are definitely off the menu during Pesach.

No doubt had there been someone at the AJN who had known this, they would have advised Costco accordingly. Sad.
