Beware the Roma Signage

If you're shopping for organic roma tomatoes soon in the Pearl Street Whole Foods and see a very large sign in front of them saying they are on sale for $1.49/lb, watch it at checkout, as they'll ring up at $2.99/lb in the system. Happened to me Wednesday and again this morning. Actually, when you think of the complexity of what goes on in these stores, it's amazing they get it right at the very high percentage that they do. The prices in the system have to be right, the signage has to match what the prices are supposed to be, the stockers have to put the right product (organic vs. conventional) behind the sign, and finally, the cashiers have to accurately identify a dazzling array of exotic veggies just by sight. It almost always works, but it's still a good idea to check your receipt.
