Agree with lotsofpulp about the sales being valid. I have found that Costco prices are not always the lowest, but that still doesn't always mean they're a bad deal. While in an ideal world, anywhere you can pick up a Brand X product Y, it should be the same, that's not actually the case anymore. (I presume Wal-Mart didn't create this reality, but they have had a disproportional role in propagating it.) Of all things, I notice that the canned black olives I buy at Costco are consistently a step up from the exact same brand at my local megamart. So even though they aren't actually that much cheaper I still prefer to buy them there.
