Costco sends us a book with sale items, monthly. The goal is to lure us in. But when the advertized, published item is unavailable, they do nothing at all to satisfy customer. They say "we do not guarantee that sales items are available." Really? You drag us in by published promise to have items, and then not even "sorry"? NO substitutes? You lose TRUST by doing it. And so a potential 5 stars shrinks to fit 2 stars.
