Beware The Imagine Broth Ring Up

The Whole Foods store on Pearl Street has a huge display (maybe five or six feet wide and several feet high) of my beloved Imagine organic broths, proclaiming them to be on sale for $2.50 each (two for $5). However, today, taken from that big display, they rang up at $3 each, also noted as a sale price. A kind person ran back to that display (facing the meat counter) and returned to confirm the two for $5 price, which was quickly adjusted on my bill. But I also want to double check the price I was charged for Blue Moose roasted red pepper hummus, which I grabbed because it was marked at a particularly good sale price that I didn't pay much attention to, yet rang up at basically $6, yikes.
