Ya, we have a Costco membership and I prefer shopping there to what we've seen at Sam's, but in this instance Sam's is far better. There were three or four styles at Costco, but they were much thinner and had that slick laminate feel vs. the stuff we got at Sam's that had that rougher finish. The Sam's stuff also had the bevel edges we preferred, whereas the costco stuff was flat surface. Of course those are more aesthetic choices, so ymmv.
